給段最簡單的java代碼 讓我新手看一下

最簡單的java代碼肯定就是這個了，如下：

public class MyFirstApp

{

public static void main(String[] args)

{

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

}

}

“hello world”就是應該是所有學java的新手看的第一個代碼了。如果是零基礎的新手朋友們可以來我們的java實驗班試聽，有免費的試聽課程幫助學習java必備基礎知識，有助教老師為零基礎的人提供個人學習方案，學習完成后有考評團進行專業(yè)測試，幫助測評學員是否適合繼續(xù)學習java，15天內(nèi)免費幫助來報名體驗實驗班的新手快速入門java，更好的學習java！

一個簡單的Java程序代碼？

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);

}

} 編譯：javac -d . Charge.java運行：java com.zpp.Charge 111
