In Java, you can use the “instanceof” keyword to determine the type of an object.

For example, you can use the following code to determine if an object belongs to a specific class:

Object obj = new String("Hello");

if(obj instanceof String) {
    System.out.println("obj是String类型");
} else {
    System.out.println("obj不是String类型");
}

If the object is an instance of the specified class, instanceof will return true; otherwise, it will return false.
