1 Check if String contains specific Character using 'contains' method

In this example,

We create a function 'containsCharacter' that takes a string and a character as input.
We use the 'contains' method of the string object to check if the character is present in the string.
If the character is found, 'true' is returned; otherwise, 'false'.
Finally, we print the result.

Java Program

// Java
public class Main {
    public static boolean containsCharacter(String str, char ch) {
        return str.contains(String.valueOf(ch));
    }

    public static void main(String[] args) {
        String str = "Hello World";
        char ch = 'W';
        boolean contains = containsCharacter(str, ch);
        System.out.println("String contains character '" + ch + "': " + contains);
    }
}

Output

String contains character 'W': true
