Class class isSynthetic() method

• isSynthetic() method is available in java.lang package.
• isSynthetic() method is used to check whether this Class is a synthetic class or not.
• isSynthetic() 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.
• isSynthetic() method does not throw an exception at the time of checking synthetic class.

Syntax:

    public boolean isSynthetic();

Parameter(s):

• It does not accept any parameter.

Return value:

The return type of this method is boolean, it returns a boolean value based on the following cases,

• It returns true, when this Class is a synthetic class.
• It returns false, when this Class is not a synthetic class.

Example:

// Java program to demonstrate the example 
// of boolean isSynthetic() method of Class

public class IsSyntheticOfClass {
    public static void main(String[] args) {
        // Create and Return String class
        String str = new String();
        Class cl1 = str.getClass();

        // We are checking the class is a
        // Synthetic class
        boolean b1 = cl1.isPrimitive();

        System.out.print("Is" + " " + cl1.getSimpleName() + " ");
        System.out.println("Synthetic class" + ": " + b1);
    }
}

Output

Is String Synthetic class: false
