简单的java程序代码 java输出语句

import java.io.BufferedReader; import java.io.IOException; import java.io.InputStreamReader; public class a{ public double test(int time) { double sum=0; int i=0,k=0; i=time%.

public class TestStar { public static void main(String[] args) { String star = "*"; for (int i = 0; i < 5; i++) { if (i == 0) { System.out.print(" " + star); System.out.println(); } if (i == .

的确好难~~但我看明白了. 例如当你输入了15个51-60的数,10个1-10的数6个11到20的数 输出为 1-10/** 11-20/* 21-30/ 31-40/ 41-50/ 51-60/*** 61-70/ 71-80/ 81-90/ 91-.

public class HelloWorld{ public static void main(String[] args){ System.out.println(＂hello world!＂); } }

Integer j,k,l; for(Integer i=102;i<=987;i++){ j=Integer.parseInt(i.toString().substring(0,1)); k=Integer.parseInt(i.toString().substring(1,2)); l=Integer.parseInt(i.toString().substring(2,3)); if(j*2==k&&j*3==l) System.out.println(i); }

public class Test { public static void main(String[] args) { MyRectangle rec = new MyRectangle(3, 5); MyRectangle square = new MySquare(4); System.out.println(rec.toString(.

大家都知道世界上最简单的JAVA程序代码是helloword程序,高手、牛人、小虾都是从这个代码开始的:public class helloword { public static void main(String args[]) { System.out.println(＂helloword＂); } }

public class Test extend Thread{ public static void main(String[] args){ int i=0; while(i<Integer.MAX_VALUE){ System.out.println(＂第“+i+”秒＂); i++; sleep(1000); }}}

public class Search { public static final int[][] array ={ {8,2,3,4,5}, {7,6,5,8,8}, {6,4,5,7,10} }; public static void main(String[] args) { for(int i=0;i<array.length;i++){ int minCol = .

public class testtxt { public static void write(file f,file f2) throws ioexception { bufferedreader br= new bufferedreader(new filereader(f)); bufferedwriter bw=new bufferedwriter(.
