JAVA第8次实验

1.for遍历：

public class Hestia {
    public static void main(String[] args){
        int[] arr={2,5,8,1,7};
        int min=arr[0];
        for (int i = 0; i < arr.length; i++) {
            if(min>arr[i]){
                min=arr[i];
            }
        }
        System.out.println("最小值："+min);
    }
}

1.foreach遍历：

public class Hestia {
    public static void main(String[] args){
        int[] arr={2,5,8,1,7};
        int min=arr[0];
        for (int i : arr) {
            if(min > i){
                min = i;
            }
        }
        System.out.println("最小值："+min);
    }
}

2.Person类

public class Person {
    private String name;
    private int age;
    private String address;

    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 String getAddress() {
        return address;
    }

    public void setAddress(String address) {
        this.address = address;
    }

    public Person() {}
    public Person(String name,int age,String address) {
        this.name=name;
        this.age=age;
        this.address=address;
    }
    public void display(){
        System.out.println("姓名："+name);
        System.out.println("年龄："+age);
        System.out.println("地址："+address);
    }
}

3.PersonDemo类

public class PersonDemo {
    public static void main(String[] args){
       Person p1=new Person("千世",16,"山东省聊城市");
        Person p2=new Person("Hestia",19,"江苏省南京市");
        System.out.println("年龄较大的是："+pd(p1,p2));
    }
    public static String pd(Person a,Person b){
        if(a.getAge()>b.getAge()){
            return a.getName();
        }else{
            return b.getName();
        }
    }
}
