this.name = name;

}

public int getAge() {

UwwTpFsZjreturn age;

}

public void setAge(int age) {

this.age = age;

}

public void marry(Girl girl) {

System.out.println(this.name+ " 也想娶：" + girl.getName());

public void shout() {

if(this.age >= 22) {

System.out.println("可以了");

}else {

System.out.println("不可以");

public void marry(Boy boy) {

System.out.println(this.name + " 想嫁给：" + boy.getName());

boy.marry(this);

}

public void compare(Girl girl) {

if(this.age > girl.getAge()) {

System.out.println(this.getName() + "比" + girl.getName() + "大");

}else if(this.age < girl.getAge()) {

System.out.println(this.getName() + "比" + girl.getName() + "小");

}else {
