Take Array input in Java language

Take Array input in Java language

In this tutorial, we will discuss the concept ofTake Array input in Java language

In this topic, we are going to learn how to input the integer array elements in Java programming language using for, while and do-while loops.

In this blog, We have already discuss that “What is an array“, type of arrays and how to access it(one dim, two dim and three dim arrays)

Arrays are the special type of variables to store Multiple type of values(int, string,char, etc)under the same name in the continuous memory location. we can be easily accessed using the indices(indexes)

Here,

• e1,e2,e3,e4 and e5 represent the integer elements of the array
• 0,1,2,3 and 4 represent the index of the array which is used to access the array elements
• 1,2,3,4 and 5 represent the length of the array

Code to input array elements in Java

Program to read elements in array using for loop

In this program, we are briefing how to input integer elements of an array using for loop in Java language

Program 1

import java.util.Scanner;
public class TakeArrayInputfor{
public static void main(String args[]){
//scanner class object to read input
    Scanner sc=new Scanner(System.in);
    //Declaring and creating array
    int[] arr=new int[5];
    
    //Display dfault value before initialize
    System.out.println("Default value of integer array: ");
    for(int i=0; i
When the above code is executed, it produces the following result
Default value of integer array:
0
0
0
0
0

*****initializing array******
Enter 5 integer value
35
58
79
95
70

*****displaying array elements******
Entered array elements are:
35
58
79
95
70



Program to read elements in array using while loop
In this program, we are briefing how to input integer elements of an array using while loop in Java language
Program 2
import java.util.Scanner;
public class TakeArrayInputwhile{
public static void main(String args[]){
//scanner class object to read input
    Scanner sc=new Scanner(System.in);
    //Declaring and creating array
    int[] arr=new int[5];
    
    //Display dfault value before initialize
    System.out.println("Default value of integer array: ");
    int i=0;
    while(i
When the above code is executed, it produces the following result
Default value of integer array:
0
0
0
0
0

*****initializing array******
Enter 5 integer value
356
876
487
890
987

*****displaying array elements******
Entered array elements are:
356
876
487
890
987
Program to read elements in array using do-while loop
In this program, we are briefing how to input integer elements of an array using do-while loop in Java language
Program 3
import java.util.Scanner;
public class TakeArrayInputDowhile{
public static void main(String args[]){
//scanner class object to read input
    Scanner sc=new Scanner(System.in);
    //Declaring and creating array
    int[] arr=new int[5];
    
    //Display dfault value before initialize
    System.out.println("Default value of integer array: ");
    int i=0;
    do{
        System.out.println(arr[i]+"\t");
         i++;
    }while(i
When the above code is executed, it produces the following result
Default value of integer array:
0
0
0
0
0

*****initializing array******
Enter 5 integer value
456
78
999
654
567

*****displaying array elements******
Entered array elements are:
456
78
999
654
567
