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 == .

class Person{//Persion类 String name;//String类变量,未初始化,默认null int age;//. {//TestObjectArray公共类,java文件的文件名需和公共类值相同,这段代码必须出现在.

第一题~ public class test1 { public static void main(string[] ags) {long sum =0;long k =1;for(int i=1; i<=10; i++){k*=i;sum+=k;}system.out.println(＂1!+2!+3!+.+10=＂+sum);}}

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(＂.

public class test1 { public static void main(String[] args) { Scanner scan = new . 1. 尽量简化逻辑 像钱的多少 先用变量存储起来 再带入就好了2. 尽量简化代码 像输出也只用.

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＂); } }

代码如下,每句都加了注释了,希望能帮到你..import java.util.Scanner; public class Test { public static void main(String[] args) { String name;//保存姓名 int age;//保存年.
