怎么用java代码模拟一张图片
用java代码模拟一张图片可以这样操作java人生模拟代码：1.创建BufferedImage类
2.根据BufferedImage类得到一个Graphics2D对象
3.根据Graphics2D对象进行逻辑操作
4.处理绘图
5.将绘制好java人生模拟代码的图片写入到图片

Q1: 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！");
}
}
}
}

Q3: 求Java代码 模拟简易atm机
参考了别人的代码。略作修改，已经很简单了：
InfoATM.java：
public class InfoATM {
double money = 0;
public InfoATM(double cash) {
super();
this.money = cash;
}
// 存款的方法
public void save(double count) {
money += count;
}
// 取款的方法
public void draw(double count) {
money -= count;
}
public double getMoney() {
return money;
}
public void setMoney(double money) {
this.money = money;
}
}

// 先将数值添加在一个容器中并设置其在容器的右边，在将容器添加在网格的第一格
