How to Append a Character to beginning of a String in Java ?

Answer

To append a character to the beginning of a string in Java, you can use string concatenation or the StringBuilder class.

✐ Examples

1 Append 'H' to "ello"

In this example,

We create a string named str1 with a value of "ello".
We then use string concatenation to append the character 'H' to str1.
String concatenation automatically converts the character to a string and concatenates it with str1.
Finally, we print the concatenated string to the console.

Java Program

public class Main {
    public static void main(String[] args) {
        String str1 = "ello";
        str1 = 'H' + str1;
        System.out.println(str1);
    }
}

Output

Hello

2 Append 'W' to "orld"

In this example,

We create a string named str2 with a value of "orld".
We then use the StringBuilder class to efficiently append the character 'W' to str2.
Finally, we print the concatenated string to the console.

Java Program

public class Main {
    public static void main(String[] args) {
        String str2 = "orld";
        StringBuilder sb = new StringBuilder(str2);
        sb.insert(0, 'W');
        System.out.println(sb.toString());
    }
}

Output

World
