编写一个jAvA程序

public class SuShu { public static void main(String[] args) { int n=0;//记录1000以内素数的个数 int m=0;//记录数字能被几个数整除 for(int i=200;i<301;i++){ for(int j=1;j<=i;j++){ if(i%j==0){ m++;//如果i能被j整除,则计一次 } } if(m==2){//如

import java.util.Date; class Telephone{ private String brand; private String phoneNum; private int seconds; private double rate; public String getBrand() { return brand; } public void setBrand(String brand) { this.brand = brand; } public String

import java.util.*; public class ManyClasses { public static void main(String args[]) { int st[]=new int[3]; for(int i=0;i<3;i++) { st[i]=Integer.parseInt( args[i]); //转换 } Arrays.sort(st); //排序 System.out.println(＂最大值=＂+st[2]); System.out.

public class Demo3 { public static void main(String[] args) { byte a =1; short b=1; int c = 1; long d = 1l; float e=1f; double f =1; char g ='1'; boolean h = true; System.out.println(＂byte a =＂+a); System.out.println(＂short b=＂+b); System.out.println(＂int

public class Test{ int length; int wide; int height; public Test() { } int cout(int a,int b,int c) { int count = 0; length = a; wide = b; height = c; count = length*wide*height; return count; } void output(int count) { System.out.println(＂体积:＂+count); } public

class Trangle{ private double a, b, c;//三个边 private double area;//面积 private double perimeter;//周长 public double getArea() {//返回面积 return area; } public double getPerimeter() {//返回周长 return a+b+c; } public void setA(double a)

楼上正解class T{ public static void main(String[] args) { if(141.2+102.3+118.9+135.1>500) System.out.println(＂已达目标＂); else System.out.println(＂未到目标＂); }} class T{ public static void main(String[] args) { for(int i=1000;i<2000;i++) if(i%3==0)System.out.print (i+＂ ＂); }}

import java.util.*; public class yugi{ public static void main(string[] args){ scanner scan = new scanner(system.in); system.out.println(＂输入班级人数:＂); int num = scan.nextint(); double sum = 0; double max = double.min_value; double min =
