MethodsJava Write the appropriate method headings using the provided method name for the following processes:1.) Given the radius of a circle, print the area of a circle - printArea. 2.) Accept an integer, compute for the square of the number and return the String equivalent of the square of the number - makeString 3.) Calculate and return the sum of two decimal numbers - getSum. 4.) Given a student’s name and three test scores (of type int), print the student’s name and average test score - printStudentDetails. 5) Compute and return the average speed of a car, given the distance traveled (as type double) and traveling time (in hours and minutes, both of type int) - getAverageSpeed.
String.substring:1 String substring(int beginIndex) // i).2 String substring(int beginIndex, int endIndex) // ii). 1. Are these two methods an example of method overloading? Briefly explain your answer. 2. What will be the output of the following code?1 "Hello".substring(5, 1); 3. What will be the output for the following code?1 String str = "USI-Lugano";2 str += "-2022";3 System.out.println(str.substring(0));4 System.out.println(str.substring(15));5 System.out.println(str.substring(4,10));6 System.out.println(str.substring(6,6)); 4. Are the 2 substring methods changing the state of the string object for which they are called. For example isstr.substring(15) changing the content of the String object str?

What value is returned from the following method? public static double methodA() { double a = 8.5 + 9.5; return a; }
For each call to the following method, indicate what value is returned: public int mystery4(int x, int y) { if (x < y) { return x; } else { return mystery4(x - y, y); } } mystery4(6, 13) mystery4(14, 10) mystery4(37, 10) mystery4(8, 2) mystery4(50, 7)
Fill in the parameters in the second method header for the overloaded method printCourse(). The number, type, and order of the method parameters are indicated in the method call from main(). Ex: If the input is 82 Ethics, then the output is: Ethics grade: 82 Immunology grade: 87 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 System.out.println(courseName+" grade: "+grade); } publicstaticvoidprintCourse(/* Your code goes here */) { System.out.println("Immunology grade: "+inputGrade); } publicstaticvoidmain(String[] args) { Scannerscnr=newScanner(System.in); intgrade; StringcourseName; grade=scnr.nextInt(); courseName=scnr.next(); printCourse(grade, courseName); printCourse(87); // Overloaded method called } }
To create a method that would give me a nicely formatted display of my information in accordance with standard convention, which method header should I use? public String tostring() public static String tostring() public String toString() public static String toString() in java
Write a method call DisplaySineTable(), that prompts the user for a starting value and an step size. The method will calculate and display a table (10 rows) of sine values based on the user input. Use the built-in method Math.Sin() to obtain the sine of an angle. e.g. if the starting value is 0.5 and the step size is 0.03 the method will display the following table:0.50 0.47940.53 0.50550.56 0.53110.77 0.6961
1). What will be returned from the following method? public static double methodXY() { double a = 6.5 + 8.5; if( a > 12) return a; else return 10; }
The following code is poorly structured. Rewrite it so that it has a better structure and avoids redundancy. To help eliminate redundancy, convert the code into a method named spending that accepts two parameters: a Scanner for the console, and a String for a single person's name, and prints the appropriate information about that person's bills. Your method could be called twice (once for John and once for Jane) to replicate the original code's behavior.
If the value passed into the parameter x in the following method is 20. What is the value returned by this method? public static int method3(int x) { int sum = 0; for(int i = 1; i <= x; i += 8) sum += i; return sum; }
This method simulates the playing of one round of “Rock Paper Scissors”. In this strange version of the game, if both players have the same hand gestures, the return value is 1. If they have different hand gestures, the return value is a 0. If at least one player, provides a string argument that is anything other than rock, paper, or scissors, the return value is -1. The method should not be case-sensitive. For example, rock, ROCK, Rock, and RocK are all valid. The output is in the image I added
