How to Append a String to another String in Java ?

Answer

To append a string to another string in Java, you can use the concat method or the += operator to concatenate the strings.

✐ Examples

1 Append " World" to "Hello"

In this example,

We create a string named str1 with a value of "Hello".
We then use the concat method to append the string " World" to str1.
The concat method concatenates the two strings and returns the result.
Finally, we print the concatenated string to the console.

Java Program

// Append " World" to "Hello"
public class Main {
    public static void main(String[] args) {
        String str1 = "Hello";
        str1 = str1.concat(" World");
        System.out.println(str1);
    }
}

Output

Hello World

2 Append "apple" to "banana"

In this example,

We create a string named str2 with a value of "banana".
We then use the += operator to append the string "apple" to str2.
The += operator concatenates the two strings and assigns the result to the variable str2.
Finally, we print the updated string to the console.

Java Program

// Append "apple" to "banana"
public class Main {
    public static void main(String[] args) {
        String str2 = "banana";
        str2 += "apple";
        System.out.println(str2);
    }
}

Output

bananaapple
