跪求大神荣光 回答下面的机器人的JAVA代码

用java代码写人生 int s = 人的生命的开始; int o = 人的生命的结束; fo

int 后面不能跟字符串。。并且for循环也不知道想要表达什么

public class Test {

public static void main(String[] args) {

double b = Math.random() * 50;

int a = (int) b + 50;

for (int i = 0; i = a; i++) {

if (i == 0) {

System.out.println("出生！");

} else {

System.out.println(i + "岁了！");

}

}

}

}

如何用JAVA定义类-人（Human），根据Human类创建如图所示对象，并输入对象信息

public class Human{

public String _name;

public String _wugong;

Human(){_name="";_wugong="";}

Human(String name, String wugong){_name=name;_wugong=wugong;}

public static void main(String[] args) {

java.util.Scanner sc = new java.util.Scanner(System.in);

java.util.ArrayListHuman list = new java.util.ArrayListHuman();

String name, wugong;

System.out.println("输入人名和武功(输入人结束)");

while(true){

System.out.print("人名：");

name = sc.next();

boolean flag = false;

for(int i = 0; i list.size(); ++i) {

if(list.get(i)._name.equals(name)){

System.out.println("此人已经存在，请重新输入");

flag = true;

}

}

if(flag) continue;

if(name.equals("人")) break;

System.out.print("武功：");

wugong = sc.next();

list.add(new Human(name, wugong));

}

System.out.println("输入人查询，输入人名查询武功，输入exit退出");

while(true){

name = sc.next();

if(name.equals("exit")) break;

if(name.equals("人")) {

System.out.println("人名：");

for(int i = 0; i list.size(); ++i) {

System.out.println(list.get(i)._name);

}

} else {

boolean flag = false;

int k = 0;

for(int i = 0; i list.size(); ++i) {

if(list.get(i)._name.equals(name)) {flag = true; k = i;}

}

if(flag) System.out.println(name + "的武功为:" + list.get(k)._wugong);

else System.out.println("查无此人");

}

}

System.out.println("谢谢使用");

}

}

测试结果是：

输入人名和武功(输入人结束)

人名：黄蓉

武功：打狗棒法

人名：郭靖

武功：降龙十八掌

人名：小龙女

武功：玉女素心剑法

人名：杨过

武功：玉女素心剑法

人名：郭靖

此人已经存在，请重新输入

人名：人

输入人查询，输入人名查询武功，输入exit退出

人

人名：

黄蓉

郭靖

小龙女

杨过

黄蓉

黄蓉的武功为:打狗棒法

我

查无此人

exit

谢谢使用

求一个最简单的在JAVA上画图形的代码。

import java.awt.*;

class MyFrame extends Frame{

MyPanel p = new MyPanel();

public MyFrame(){

this.add(p);

this.setSize(300,300);

//省略了关闭窗口的代码

this.setVisible(true);

}

public static void main(String[] args){

new MyFrame();

}

class MyPanel extends Panel

{

public void paint(Graphics g){

g.drawLine(0,0,300,300);

}

}

}
