• isSynthetic() method is available in java.lang package.

  isSynthetic()方法在java.lang包中可用。

• isSynthetic() method is used to check whether this Class is a synthetic class or not.

  isSynthetic()方法用于檢查此Class是否為合成類。

• 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()方法是一個非靜態方法，只能通過類對象訪問，如果嘗試使用類名稱訪問該方法，則會收到錯誤消息。

• isSynthetic() method does not throw an exception at the time of checking synthetic class.

Parameter(s):

// 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);
}
}
