- Methods Details: public static java.lang.StringBuffer[] getArrayStringsLongerThan(java.lang.StringBuffer[] array, int length) Returns a StringBuffer array with COPIES of StringBuffer objects in the array parameter that have a length greater than the length parameter. If no strings are found an empty array will be returned. Parameters: array - length - Returns: Throws:java.lang.IllegalArgumentException - When a null array parameter is providedjava: Run length coding is a method to represent a string in a more compact manner. Each character that occurs more than 2 times in a row is represented by the character and a number following it. Two examples are: "abba" → "abba""abcccbbbba" → "abc3b4a"Write a function that calculates how many characters the encoded string is shorter than the original.Write a program in Java programming language that reads an array of strings!The program should write all the strings from array that have at least one letter 'a'.
- For any element in keysList with a value smaller than 50, print the corresponding value in itemsList, followed by a space. Ex: If the input is: 32 105 101 35 10 20 30 40 the output is: 10 40 import java.util.Scanner; public class Compare { public static void main(String args[]) { final int SIZE_LIST = 4; int[] keysList = new int[SIZE_LIST]; int[] itemsList = new int[SIZE_LIST]; int i; Scanner input = new Scanner(System.in); keysList[0] = input.nextInt(); keysList[1] = input.nextInt(); keysList[2] = input.nextInt(); keysList[3] = input.nextInt(); itemsList[0] = input.nextInt(); itemsList[1] = input.nextInt(); itemsList[2] = input.nextInt(); itemsList[3] = input.nextInt(); //answer// System.out.println(); } }For any element in keysList with a value greater than 40, print the corresponding value in itemsList, followed by a semicolon (no spaces). Ex: If the input is: 32 105 101 35 10 20 30 40 the output is: 20;30; import java.util.Scanner; public class Compare { public static void main(String args[]) {final int SIZE_LIST = 4;int[] keysList = new int[SIZE_LIST];int[] itemsList = new int[SIZE_LIST];int i;Scanner input = new Scanner(System.in); keysList[0] = input.nextInt();keysList[1] = input.nextInt();keysList[2] = input.nextInt();keysList[3] = input.nextInt(); itemsList[0] = input.nextInt();itemsList[1] = input.nextInt();itemsList[2] = input.nextInt();itemsList[3] = input.nextInt(); /* Your code goes here */ System.out.println();} }(Java) Write a program that uses String method regionMatches to compare two strings input by the user. The program should prompt the user to enter two strings, the starting index in the first string, the starting index in the second string, and the number of characters to be compared. The program should print whether or not the strings are equal. (Ignore the case of the characters during comparison.) Standard output: Enter·first·string:Enter·second·string:Enter·starting·index·for·first·string:Enter·starting·index·for·second·string:Enter·number·of·characters·to·be·compared:true↵
- java getDup accepts an array and returns an int. If there is any element is duplicated, the method counts how many of those present in the array.
