How to make copy of a string in Java

In this tutorial, we are going to learn about two different ways to copy a string in Java.

Copying the string

Consider, we have the following string:

str = 'hello'

To make a copy of a string, we can use the built-in new String() constructor in Java.

Example:

public class Main
{
    public static void main(String[] args) {
        String s = "hello";
        String copy = new String(s);
        System.out.println(copy);
    }
}

Similarly, we can also copy it by assigning a string to the new variable, because strings are immutable objects in Java.

public class Main
{
    public static void main(String[] args) {
        String s = "hello";
        String copy = s;
        System.out.println(copy);
   }
}
