The document contains a Java program named 'arrayoperations' for performing various operations on an array of doubles. It includes functionalities for inputting array elements, printing arrays, calculating square roots, replacing values, and copying arrays. The main method orchestrates these operations and displays results at each step.

1. ArrayOperations.java
import java.util.Arrays;
import java.util.Scanner;
public class ArrayOperations {
/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub
double arr[] = input();
System.out.println("Input Array Elements: ");
printArray(arr);
getSquarRoot(arr);
System.out.println("After Square root method called:");
printArray(arr);
replaceValue(arr);
System.out.println("After replace method called:");
printArray(arr);
double arr1[] = copyArray(arr);
System.out.println("Original Array:");
printArray(arr);
System.out.println("New Array:");
printArray(arr1);
}
public static double[] input(){
double arr[] = new double[10];
Scanner scan = new Scanner(System.in);
for(int i=0; i 500)
arr[i] = 500;
}
}
public static double[] copyArray(double arr[]){
double arr1[] = new double[arr.length];

2. for(int i=0; i
