In this post, we will learn to code the Java Program to Print 1 to 100 Without Using Loops. Let’s understand How to print 1 to 100 without using loop in Java Programming Language.
Java Program to Print 1 to 100 Without Using Loop
We can achieve the desired result of printing 1 to 100 without a loop by using the concept of recursion and recursive functions.
import java.util.*;
public class Main{
public static void printFrom1To100(int N){
// Base Condition
if(N == 100){
System.out.println(100);
return;
}
System.out.print(N+" ");
printFrom1To100(N+1);
}
public static void main(String[] args){
printFrom1To100(1);
}
}
Output
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 64 65 66 67 68 69 70 71 72 73 74 75 76 77 78 79 80 81 82 83 84 85 86 87 88 89 90 91 92 93 94 95 96 97 98 99 100How Does This Program Work ?
In this program, we used the concept of Recursion and we created a recursive function to print from 1 to 100 without using loop.
public static void printFrom1To100(int N){
// Base Condition
if(N == 100){
System.out.println(100);
return;
}
System.out.print(N+" ");
printFrom1To100(N+1);
}
We have created a recursive function printFrom1To100() with the base condition if N is equal to 100 then we print 100 and return. For every N value, we print the value and then call the recursive function with the value N+1 till N becomes 100.
We call the function from the main function with the initial passing value of N as 1.
public static void main(String[] args){
printFrom1To100(1);
}
So, the program executes and the recursive function is called with initial value 1.
Then, in the function, N is not equal to 100. i.e. N = 1. so, the code then prints the value 1 and then calls the function with the value N+1 i.e. N=2.
Then, N=2, and N is not equal to 100. Again we print the value 2 and then call the function with the value N+1 i.e. 3. Similarly this goes on till N becomes 100.
When N = 100, the Base condition is fulfilled, and then the function prints the value of 100 and returns from the function.
This is the Java Program to Print 1 to 100 Without Using Loop.
