给段最简单的java代码 让我新手看一下

最简单的java代码肯定就是这个了，如下：

public class MyFirstApp

{

public static void main(String[] args)

{

System.out.print("Hello world");

}

}

“hello world”就是应该是所有学java的新手看的第一个代码了。如果是零基础的新手朋友们可以来我们的java实验班试听，有免费的试听课程帮助学习java必备基础知识，有助教老师为零基础的人提供个人学习方案，学习完成后有考评团进行专业测试，帮助测评学员是否适合继续学习java，15天内免费帮助来报名体验实验班的新手快速入门java，更好的学习java！

一个简单的Java程序代码？

package com.zpp;public class Charge {

public static void main(String [] args) {

if(args.length ==0) {

System.out.println("parameter error!");

System.out.println("java com.zpp.Charge [int]");

return;

}

int min = Integer.parseInt(args[0]);

double money = 0.0;

if (min = 0) {

money =0.0;

System.out.println("not money");

} else if (min = 60) {

money = 2.0;

} else {

money = 2.0 + (min - 60) * 0.01;

}

System.out.println("please pay: " + money);

}

} 编译：javac -d . Charge.java运行：java com.zpp.Charge 111
