Sample Java Program to Print 1 to 100 without Loop

Write a Sample Java Program to Print 1 to 100 without using For Loop, While and Do While Loop with example.

Sample Java Program to Print 1 to 100 without Loop

In the example, we are going to write a Java Program to return numbers from 1 to 100 without using Loops.

// Sample Java Program to Print 1 to 100 without Loop 
public class print1to100 {
	public static void main(String[] args) 
	{
		int number = 1;
		
		printNumbers(number);	
	}
	
	public static void printNumbers(int num)
	{
		if(num <= 100)
		{
			System.out.print(num +" "); 
			printNumbers(num + 1);
		}	
	}
}

Within the method, we used the If Statement to check whether the number is less than or equal to 100 or not. If the condition returns TRUE, then the code inside the If statement executed.

if(num <= 100)
{
	System.out.print(num +" "); 
	printNumbers(num + 1);
}

Within the If block, we used the print number(number + 1) statement, which helps to call the same method with the updated value. If you miss this Java statement, then after completing the first line, it terminates, and the output is 1.

Sample Java Program to return 100 to 1 without Loop

In the example, we are going to write a JavaProgram to display numbers from 100 to 1 without using Loops.

// Sample Java Program to Print 100 to 1 without Loop 
public class print1to100Ex2 {
	public static void main(String[] args) 
	{	
		printNumbers(100);	
	}
	
	public static void printNumbers(int num)
	{
		if(num > 0)
		{
			System.out.print(num +" "); 
			printNumbers(num - 1);
		}	
	}
}
