How to Format Given String in Java

In this example, we will write an example to help format a given string in Java through format () method.

Source Code

package com.beginner.examples;

public class StringFormatter {
	public static void main(String[] args) {
			
		//%s stands for string
		String str = "I like %s";
		
		//Print the formatted string
		System.out.println(String.format(str, "java"));
		
		//%d stands for integer 
		String str1 = "20 + 2 = %d";
		
		System.out.println(String.format(str1, 22));
		
		//%f stands for float
		String str2 = "2.1 + 0.1 = %f";
		
		System.out.println(String.format(str2, 2.2));
	
	}
