对象数组

package Object;

public class Student {
	public String name;
	public int age;
	
	@Override
	public String toString() {
		return "Student [name=" + name + ", age=" + age + "]";
	}
}

package Object;
public class Shuzu {		
	public static void main(String[] args){
		Student stu[]=new Student[5];	
		Student student1=new Student();
			
		student1.name="young";
		student1.age=20;
	
		stu[0]=student1;
		System.out.println(stu[0]);	
	}		
}

通过输入给数组对象

package Object;

import java.util.Scanner;

public class Shuzu {
	
	
	public static void main(String[] args){
		
		Student stu[]=new Student[5];	
	
		Scanner scanner=new Scanner(System.in);
		for(int i=0;i<stu.length;i++){
			Student student1=new Student();
			System.out.println("第"+(i+1)+"个学生的姓名");
			student1.name=scanner.next();
			System.out.println("第"+(i+1)+"个学生的年龄");
			student1.age=scanner.nextInt();
		
			stu[i]=student1;		
	} 
		//遍历	
		for(int i=0;i<stu.length;i++){
		System.out.println(stu[i]+"\t");
	}
	
	}
		
}
