Comparing Arrays : Java Util

     

This section show you how to determine the given arrays are same or not. The given program illustrates you how to compare arrays according to the content of the that.

In this section, you can see that the given program initializes two arrays and input five number from user through the keyboard. And then  the program checks whether the given taken both arrays are same or not. This comparison operation is performed by using the equals() method of Arrays class.

Arrays.equals():
Above method compares two arrays.

Arrays is the class of the java.util.*; package. This class and it's methods are used for manipulating arrays.

Here is the code of the program:

import java.io.*;
import java.util.*;

public class ComparingArrays{
  public static void main(String[] argsthrows IOException{
  int[] array1 = new int[5];
  int[] array2 = new int[5];
  BufferedReader in = new BufferedReader(new InputStreamReader(System.in));
  try{
  System.out.println("Enter 5 numbers for the first Array : ");
  for(int i = 0; i < array1.length; i++){
  array1[i= Integer.parseInt(in.readLine());
  }
  System.out.println("Enter 5 numbers for the second Array : ");
  for(int i = 0; i < array2.length; i++){
  array2[i= Integer.parseInt(in.readLine());
  }
  }
  catch(NumberFormatException ne){
  ne.printStackTrace();
  }

  boolean check = Arrays.equals(array1, array2);
  if(check == false)
  System.out.println("Arrays are not same.");
  else
  System.out.println("Both Arrays are same.");
  }
}
