How to read user input for integer array using Java

In this article, we will discuss the concept of How to read user input for integer array using Java

In this post, we are going to learn how to write a program to  input  integer in an array from user  in Java language   using for, while and do-while  loop

Code to input integer for an array

Code to input integer for an array using for loop

In this code, we are going to learn how to input integer in an array using for loop in Java language

Program 1

import java.util.Scanner;
public class AcceptArrayInputfor{
public static void main(String args[]){
//scanner class to read input from the user
  Scanner sc=new Scanner(System.in);
  //Declaring and creating array
  int[] arr=new int[6];
  
  //Display default value before initializing
  System.out.println("Default values of 6 elements in this array: ");
  for(int i=0; i<arr.length; i++){
    System.out.println(arr[i]);
  }//print default value of the given array
  System.out.println("");
  //initializing value to the array
  System.out.println("******Initializing 6 elements of the array******");
  System.out.println("Enter "+arr.length+" integer values");
  for(int i=0; i<arr.length; i++){
    arr[i]=sc.nextInt();
  }//using the for loop to initializing array
  
  //displaying the array
  System.out.println("\n******displaying given 6 array elements******");
  System.out.println("Entered array elements are");
  for(int i=0; i<arr.length; i++){
    System.out.println(arr[i]+"\t");
  }
}
}

When the above code is executed, it produces the following result

Code to input integer for an array using while loop

In this code, we are going to learn how to input integer in an array using while loop in Java language

Program 2

import java.util.Scanner;
public class AcceptArrayInputwhile{
public static void main(String args[]){
//scanner class to read input from the user
  Scanner sc=new Scanner(System.in);
  //Declaring and creating array
  int[] arr=new int[6];
  
  //Display default value before initializing
  System.out.println("Default values of 6 elements in this array: ");
  int i=0;
  while(i<arr.length){
    System.out.println(arr[i]);
     i++;
  }//print default value of the given array
  System.out.println("");
  //initializing value to the array
  System.out.println("******Initializing 6 elements of the array******");
  System.out.println("Enter "+arr.length+" integer values");
  i=0; 
  while(i<arr.length){
    arr[i]=sc.nextInt();
     i++;
  }//using the for loop to initializing array
  
  //displaying the array
  System.out.println("\n******displaying given 6 array elements******");

  i=0;
  while(i<arr.length){
    System.out.println(arr[i]+"\t");
     i++;
  }
}
}

Code to input integer for an array using do-while loop

In this code, we are going to learn how to input integer in an array using do-while loop in Java language

Program 1

import java.util.Scanner;
public class AcceptArrayInputdowhile{
public static void main(String args[]){
//scanner class to read input from the user
  Scanner sc=new Scanner(System.in);
  //Declaring and creating array
  int[] arr=new int[6];
  
  //Display default value before initializing
  System.out.println("Default values of 6 elements in this array: ");
  int i=0;
  do{
    System.out.println(arr[i]);
     i++;
  }while(i<arr.length);
  //print default value of the given array
  System.out.println("");
  //initializing value to the array
  System.out.println("******Initializing 6 elements of the array******");
  System.out.println("Enter "+arr.length+" integer values");
  i=0; 
  do{
    arr[i]=sc.nextInt();
     i++;
  }while(i<arr.length);
    //using the do-while loop to initializing array
  
  //displaying the array
  System.out.println("\n******displaying given 6 array elements******");
  System.out.println("Entered array elements are");
  i=0;
  do{
    System.out.println(arr[i]+"\t");
     i++;
  }while(i<arr.length);
}//display elements using do-while loop
}

When the above code is executed, it produces the following result
