How to do string formatting with placeholders in Java (like in Python)?

Question

I am new to Java and am from Python. In Python we do string formatting like this:

>>> x = 4
>>> y = 5
>>> print(\"{0} + {1} = {2}\         


        

Answer 1

Java has a String.format method that works similarly to this. Here's an example of how to use it. This is the documentation reference that explains what all those % options can be.

And here's an inlined example:

package com.sandbox;

public class Sandbox {

    public static void main(String[] args) {
        System.out.println(String.format("It is %d oclock", 5));
    }        
}

This prints "It is 5 oclock".
