***JAVA PROGRAM

Write a method called shrink that accepts an array of integers (that the user inputs) as a parameter and returns a new array containing the result of replacing each pair of integers with the sum of that pair. For example, if an array called list stores the values {7, 2, 8, 9, 4, 15, 7, 1, 9, 10}, then the call of shrink(list) should return a new array containing {9, 17, 19, 8, 19}.

The first pair from the original list is shrunken into 9 (7 + 2),

the second pair is shrunken into 17 (8 + 9), and so on.

If the list stores an odd number of elements, the final element is not collapsed. For example, if the list had been {1, 2, 3, 4, 5}, then the call would return {3, 7, 5}. Your method should not change the array that is passed as a parameter.

Be sure to have a shrink() method

*All variable names are completely up to you, as long as they’re descriptive

*Use the correct data types

*Use comments to explain what you’re coding

*Put your name in a comment

import java.util.Arrays;

public class ArrayShrinkExample {
   public static void main(String[] args) {
           int arr[]={7, 2, 8, 9, 4, 15, 7, 1, 9, 10};
           System.out.println(Arrays.toString(shrink(arr)));
           int arr2[]={1, 2, 3, 4, 5};
           System.out.println(Arrays.toString(shrink(arr2)));

   }
   public static int [] shrink(int arr[]) {
       int size;
       if(arr.length%2==0)
           size=arr.length/2;
       else
           size=arr.length/2+1;
       int res[]= new int[size];

       for(int i=0,j=0;i<arr.length-1;i+=2,j++) {
           res[j]=arr[i]+arr[i+1];
       }
       if(arr.length%2==1) {
           res[res.length-1]=arr[arr.length-1];
       }
       return res;
   }

use java for : 1. Write a method called indexOfMax that takes an array of integers and returns the index of the largest element. 2. The Sieve of Eratosthenes is “a simple, ancient algorithm for finding all prime numbers up to any given limit” (https://en.wikipedia. org/wiki/Sieve_of_Eratosthenes).Write a method called sieve that takes an integer parameter, n, and returns a boolean array that indicates, for each number from 0 to n -1, whether the number is prime.

Write a Java program that reads a list of integers into an array. The program should read this array from the file “input.txt”. You may assume that there are fewer than 50 entries in the array. Your program determines how many entries there are. The output is a two-column list. The first column is the list of the distinct array elements; the second column is the number of occurrences of each element. The list should be sorted on entries in...

JAVA Write a test program that prompts the user to enter a series of integers and displays whether the series contains runLength consecutive same-valued elements. Your program’s main() must prompt the user to enter the input size - i.e., the number of values in the series, the number of consecutive same-valued elements to match, and the sequence of integer values to check. The return value indicates whether at least one run of runLength elements exists in values. Implement the test...

IN JAVA Write a program with a method that returns an array. The method should accept as input a comma-delimited string with three values from a user. The array should store each value in a different element. Use Try..Catch error handling and print any failure messages, or print success from within method if the execution is successful (see Chapter 13 in the text). Call the method from the main method of the program to demonstrate its functionality by looping through...
