初步认识数组

package cn.jsh.arrays;

public class Test01 {
	public static void main(String[] args) {
		int arr01[] = new int[10];
		String arr02[] = new String[10];
		
		
		arr01[0] = 11;
		arr01[1] = 13;
		arr01[2] = 15;
		
		for(int i = 0;i < arr01.length;i++) {
			arr01[i] = i;
		}
		for(int i = 0;i < arr01.length;i++) {
			System.out.println(arr01[i]);
		}
		
		
		User arr03[] = new User[3];
		arr03[0] = new User(1001,"季");//2创建对象，并把地址赋给按让人【0】
		arr03[1] = new User(1001,"少");
		arr03[2] = new User(1001,"华");
		for(int i = 0;i < arr03.length;i++) {
			System.out.println(arr03[i].getName());//3调用
		}
	}

}

class User{
	private int id;
	private String name;
	
	//1创建构造器（这一步很重要）
	public User(int id, String name) {
		super();
		this.id = id;
		this.name = name;
	}
	
	public int getId() {
		return id;
	}
	public void setId(int id) {
		this.id = id;
	}
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	
	
}
