Java Program to Print Array Elements

In this article, we will show you, How to write a Java Program to Print Array Elements. Or write a Java program to Print Elements in an Array using For Loop, While Loop, and Functions with example.

Java Program to Print Array Elements using For Loop

This program in Java allows the user to enter the Size, and elements of an Array. Next, we are using For Loop to iterate each and every element in this array, and print those array elements.

// Java Program to Print Array Elements using For Loop
import java.util.Scanner;

public class PrintArray1 {
	private static Scanner sc;
	public static void main(String[] args) 
	{
		int i, Number;
		sc = new Scanner(System.in);
	 
		System.out.print(" Please Enter Number of elements in an array : ");
		Number = sc.nextInt();	
		
		int [] Array = new int[Number];
		
		System.out.print(" Please Enter " + Number + " elements of an Array  : ");
		for (i = 0; i < Number; i++)
		{
			Array[i] = sc.nextInt();
		}     
	 
		System.out.println("\n **** Elements in this Array are  **** ");
		for (i = 0; i < Number; i++)
		{
			System.out.print(Array[i] + "\t");
		}
	}
}

ANALYSIS

Here, For Loop will make sure that the number is between 0 and maximum size value. In this example, it will be from 0 to 7

for(i = 0; i < Size; i ++)

First Iteration: for (i = 0; 0 < 6; 0++)
Condition is True so, compiler will print first element(6)  in this array

Second Iteration: for (i = 1; 1 < 6; 1++)
Condition is True – compiler will print second element (15)

Third Iteration: for (i = 2; 2 < 6; 2++)
Condition is True so, compiler will print third second element (25)

Fourth Iteration: for (i = 3; 3 < 6; 3++)
Condition is True so, compiler will print fourth element (35)

Fifth Iteration: for (i = 4; 4 < 6; 4++)
Condition is True so, compiler will print fourth element (45)

Sixth Iteration: for (i = 5; 5 < 6; 5++)
Condition is True so, compiler will print fourth element (55)

Seventh Iteration: for (i = 6; 6 < 6; 6++)
Condition is False so, compiler will exit from the for loop

Java Program to Print Array Elements using While Loop

This program is same as above but this time we used While Loop to print array elements

// Java Program to Print Array Elements using While Loop
import java.util.Scanner;

public class PrintArray2 {
	private static Scanner sc;
	public static void main(String[] args) 
	{
		int i = 0, j = 0, Number;
		sc = new Scanner(System.in);
	 
		System.out.print(" Please Enter Number of elements in an array : ");
		Number = sc.nextInt();	
		
		int [] Array = new int[Number];
		
		System.out.print(" Please Enter " + Number + " elements of an Array  : ");
		while (i < Number)
		{
			Array[i] = sc.nextInt();
			i++;
		}     
	 
		System.out.println("\n **** Elements in this Array are  **** ");
		while (j < Number)
		{
			System.out.print(Array[j] + "\t");
			j++;
		}
	}
}

OUTPUT

Java Print Array Elements using Functions

This program is same as the first example, but we used a separate method to place the logic for printing array elements.

// // Java Program to Print Array Elements using Functions
import java.util.Scanner;

public class PrintArray3 {
	private static Scanner sc;
	public static void main(String[] args) 
	{
		int i, Number;
		sc = new Scanner(System.in);
	 
		System.out.print(" Please Enter Number of elements in an array : ");
		Number = sc.nextInt();	
		
		int [] Array = new int[Number];
		
		System.out.print(" Please Enter " + Number + " elements of an Array  : ");
		for (i = 0; i < Number; i++)
		{
			Array[i] = sc.nextInt();
		}     
		printAttay(Number, Array);
	}
	
	public static void printAttay(int Number, int[] Array)
	{
		int i;
		
		System.out.println("\n **** Elements in this Array are  **** ");
		for (i = 0; i < Number; i++)
		{
			System.out.println(" Element at Array["+ i +"] = " + Array[i]);
		}
	}
}

Java Print Array Elements using Recursive Methods

This program is same as the above but this time we are calling the method Recursively with updated values.

// Java Program to Print Array Elements using Recursive Method
import java.util.Scanner;

public class PrintArray4 {
	private static Scanner sc;
	public static void main(String[] args) 
	{
		int i, Number;
		sc = new Scanner(System.in);
	 
		System.out.print(" Please Enter Number of elements in an array : ");
		Number = sc.nextInt();	
		
		int [] Array = new int[Number];
		
		System.out.print(" Please Enter " + Number + " elements of an Array  : ");
		for (i = 0; i < Number; i++)
		{
			Array[i] = sc.nextInt();
		}     
		printAttay(Array, 0, Number);
	}
	
	public static void printAttay(int[] Array, int Start, int Size)
	{
		if(Start >= Size)
		{
			return;
		}
		
		System.out.println(" Element at Array["+ Start +"] = " + Array[Start]);
		printAttay(Array, Start + 1, Size);
	}
}
