getclass（）方法

getclass（）方法

public final class <?> get Class(){}

返回引用中储存的对象类型

应用：通常用于判断两个引用中实际存储对象

public class Student {
private String name;
private int age;
public Student(){

}

public Student(String name, int age) {
    this.name = name;
    this.age = age;
}

public String getName() {
    return name;
}

public void setName(String name) {
    this.name = name;
}

public int getAge() {
    return age;
}

public void setAge(int age) {
    this.age = age;
}

}

public class TestStudent {
public static void main(String[] args) {
Student s1 = new Student("aaa",20);
Student s2 = new Student("bbb",22);
//判断s1和s2是不是同一个类型
Class class1=s1.getClass();
Class class2=s2.getClass();
if (class1==class2){
System.out.println("s1和s2属于同一个类型");
}else {
System.out.println("s1和s2不属于同一个类型");
}
}
