如下所示Strings1=args[0];Strings2=args[1];Strings3=args[2];inta1=Integer.parseInt(s1);inta2=Integer.pars

不罗嗦直接给你个代码,注释看不懂就问,改变东西的话,就换arr[]里面的东西就行publicclassjuzheng{publicstaticvoidmain(Stringargs[]){intarr

最简单的：publicclassHelloJava{publicstaticvoidmain(String[]args){System.out.println("*******************

如图：

importjava.util.Scanner;publicclassTest{publicstaticvoidmain(String[]args){Scannerinput=newScanner(S

除非你自定义函数,不然是不大可能的

inth=5;//行数intx=65;//开始字符for(inti=1;i

汗.比二楼慢了一步.不过还是有点差异的.publicclassTest{publicstaticvoidmain(String[]args){int[][]a=newint[][]{{0,1,2,3,
