编写java的Application程序先送100分4个都完成再加100分(急)

public class Test{ public static void main(String args[]) { java.util.Scanner input = new java.util.Scanner(System.in); System.out.print("应付:"); int oughtPay = input.

import java.io.*; import java.util.*; import java.text.*; class CreateFile{ static public void main(String[] str) throws IOException{ File root=new File("D:/"); SimpleDateFormat

importjava.awt.*;importjava.awt.event.*;importjavax.swing.*;importjava.io.*; jf=newJTextField("d:\\BASETRANS.JAVA"); jp.setBounds(10,10,300,200); jf.setBounds(10,

//我来写个另类的- - public static void main(string[] args) { int n=9; //从1到n的结果 system.out.println(n*(1+n)/2); }

public class NumCalc { public static void main(String args[]){ int a=9, b =2; for(int i=0; i<b; i++){ a*=a; } System.out.println("result="+ a); String sa = String.valueOf(a); for(int i=sa.length()-1; i>-1; i--){ System.out.print(sa.charAt(i)); } System.out.println(); }}

Java Application 源程序文件的扩展名为( .java);如果利用编译器对源文件进行编译,编译后将产生相应的字节码文件,这些字节码文件的扩展名为(.class ). 如果一

public class App { public static void main(String args[ ]){ for(int i=0;i

import java.util.Arrays;import java.util.Scanner; public class test1 { /** * @param args */ public static void main(String[] args) { // TODO Auto-generated method stub Scanner s

/** * 学生类 * @author Shurrik */ public class Student { private String sid; private String { this.grade = grade; } }----------------------偶是分割线------------------------ import java.io.

public class Student{ private String name; private char sex; private long id; private String classinfo; private String address; public void Student(String name,char sex,long id)
