1，能给我一个最简单的java程序代码吗java语言：public class XXX{public static void main(String args[]){system.out.println("Hello world!");}}public class 11{public static void main(String args[]){ system.out.println("Hello world!");}}public String str()
2 ， 一个简单的JAVA程序编写public class test2 public static void main(String[] args) String sName[]= new String[] //输出上面的三行 for(int i = 2; i >= 0; i--)for(int j = 0; j < i ; j++)System.out.print(" "); } for(int n = 0; n < 5 - 2 * i; n++)System.out.print(sName[i]); } System.out.println(""); } //输出下面的两行 for(int i = 1; i < 3; i ++)for(int j = 0; j < i ; j++)System.out.print(" "); } for(int n = 0; n < 5 - 2 * i; n++)System.out.print(sName[i+2]); } System.out.println(""); } }}【一个简单的java程序代码，能给我一个最简单的java程序代码吗】
