StringBuilder Class appendCodePoint() method

• appendCodePoint() method is available in java.lang package.
• appendCodePoint() method is used to append the given code point parameter in the form of string to the contents of this continuation.
• appendCodePoint() method is a non-static method, it is accessible with the class object only and if we try to access the method with the class name then we will get an error.
• appendCodePoint() method does not throw an exception at the time of appending the given parameter to the given sequence.

Syntax:

    public StringBuilder appendCodePoint(int cp);

Parameter(s):

• int cp – represents the Unicode code point.

Return value:

The return type of this method is StringBuilder, it returns reference to this StringBuilder object.

Example:

// Java program to demonstrate the example 
// of StringBuilder appendCodePoint(int cp)
// method of StringBuilder 

public class AppendCodePoint {
    public static void main(String[] args) {
        // Creating an StringBuilder object
        StringBuilder st_b = new StringBuilder("Java");

        // Display StringBuilder object value
        System.out.println("st_b = " + st_b);

        // By using appendCodePoint() method to append code point 
        // like string to st_b object
        st_b = st_b.appendCodePoint(50);

        // Display StringBuilder object value
        System.out.println("st_b.appendCodePoint(60) = " + st_b);
    }
}

Output

st_b = Java
st_b.appendCodePoint(60) = Java2
