- JAVA program Write a Java program that asks the user to enter an array of integers. The program should prompt the user for the number of elements in the array and then the elements of the array. The program should then call a method named minGap that accepts the array entered by the user as a parameter and returns the minimum 'gap' between adjacent values in the array. The main method should then print the value returned by the method. The gap between two adjacent values in an array is defined as the difference in value between the first element and the second element. For example, suppose the user entered the following array of integers {1, 3, 6, 5, 12} The first gap is 2 (3 - 1), the second gap is 3 (6 - 3), the third gap is 1 (6 - 5) and the fourth gap is 5 (12 - 6). Thus, the call of minGap(array) should return 1 because that is the smallest gap in the array. If you are passed an array with fewer than 2 elements, you should return 0. Use Math.abs()JAVA program Write a Java program that asks the user to enter an array of integers.

Thus, the call of minGap(array) should return 1 because that is the smallest gap in the array. If you are passed an array with fewer than 2 elements, you should return 0.Pseudocode for Java code Write the algorithm in pseudocode for a method that accepts three parameters: an integer array, an integer representing the number of valid values in the array, and an integer representing a factor. The method will count the number of valid values in the array that are multiples of the factor and will return the count. There is a Java operator that might be very helpful in solving this problem. Testing Above problem: Assuming that the first two parameters are an array containing 4, 10, 15, 12, 8, 20, 100, 25, 32, 7, 28, and 48 and the number 12, come up with three good test cases for the factor and the return value. factor numMultiples
- Java Programming : At a fun fair, a street vendor is selling different colours of balloons. He sells N number of different colours of balloons (B[]). The task is to find the colour (odd) of the balloon which is present odd number of times in the bunch of balloons. Note: If there is more than one colour which is odd in number, then the first colour in the array which is present odd number of times is displayed. The colours of the balloons can all be either upper case or lower case in the array. If all the inputs are even in number, display the message 'All are even'. Example 1: 7 -> Value of N [r,g,b,b,g,y,y] -> B[] Elements B[0] to B[N-1], where each input element is separated by new line. Output: r -> [r,g,b,b,g,y.y] →> 'r' colour balloon is present odd number of times in the bunch. Explanation: From the input array above: r: 1 balloon g: 2 balloons b: 2 balloons y: 2 balloons Hence, r is only the balloon which is odd in number.TableAA.java Write a program that will store a multiplication table in a 2-D array. The user will enter how many lines (rows) it will have. The table will be printed to the screen. (Make it look nice – consider using printf.) This program will contain a static method. This method will take in an integer (the user’s number) and it will return a 2-D array. The code inside of the method will create the array, fill it with all the appropriate values that one would expect in a multiplication table, and then return that filled array. In the main method, you will ask the user how many lines they want to see and then you will use your static method to get the array. Once you have the array back from the static method, use nested for loops to print it in table form. See samples on the following pages. Program only needs to run once. Add try/catches so the user can only enter positive integers (1 and higher).in java create a two-dimensional array of type double to contain the three different SD Marks (JD521, PRG521, and IP521) for six different students. A single array of type String must be used to store the student names (Maxwell, Carl, Gerhard, Paul, James, and Cena). Allow a user to enter in a number, ranging from 1 to 6, which will represent the student position in the table MCSD max and present the marks for each respecting module. The program can only stop when the user enter a number greater than 6. Printout the student name including the JD521, PRG521, and IP521 max, the total of marks and the average of all marks. Use a condition statement to decide that the student has passed or not (Pass rate is 70).
- Write an application that stores nine integers in an array. Display the integers from first tolast, and then display the integers from last to first.Write the followingmethod that tests whether a two-dimensional array has four consecutive numbersof the same value, either horizontally, vertically, or diagonally:public static boolean isConsecutiveFour(int[ ][ ] values) Write a test program that prompts the user to enter the number of rows andcolumnsof a two-dimensional array then the values in the array, and displays trueif the array contains four consecutive numbers with the same value. Otherwise,the program displays false. Here are some examples of the true cases:Write a program in Java programming language that reads an array of strings! The program should write all the strings from array that end with letter 'a'.
- JAVAWrite a program that searches person's name and display all matched name. For example, if a user inputs the letter "Davis", the program searches all name which includes "Davis" in an array. Then, display all matched names on the screen. You must declare a single dimensional array which has all people’s name. Use methods of string classJavanetbeans Use a one-dimensional array to solve the following problem: Write an application that inputs five numbers each of which is between 10 and 100, inclusive. As each number is read, display it only if it is not a duplicate of a number already read. Provide the “worst case”, in which all five numbers are different. Use the smallest possible array to solve this problem. Display the complete set of unique values input after the user inputs each new value Initialize the integer array numbers to hold five elements. This is the maximum number of values the program must store if all values are input. 2. Validate the input and display an error message if the user inputs invalid data. 3. If the number entered is not unique, display a message to the user; otherwise, store the number in the array and display the list of unique numbers entered so far.The Sports Department of an education institution collects students' names participating in various teams like cricket, football, hockey. A student is allowed to participate in only ONE team. Write a Java program that prompts the user to input names for the three teams and checks NO identical names are found in the arrays. i.e., while entering name for the second team, it should not appear in the first team and while entering name for the third team, it should not appear in first and second team.
