我尝试了什么：



for（int row = 1; row< = 10; row ++）{



for（int column = 1; column< = 10; column ++）{



if（column 1 = 10） {

System.out.print（x）;

} //结束if else



} //结束列

} //结束行

What I have tried:

for (int row = 1; row <= 10; row++){

for (int column = 1; column <= 10; column++) {

if(column 1=10){
System.out.print( "x");
}//end if else

}//end column
}//end row

推荐答案

你真的不需要如果声明：

You really don't need if statements:

public static void main(String arg[])
 {
   for (int r = 0; r < 10; ++r)
   {
     for (int c = 0; c < 10; ++c)
       System.out.print('X');
     System.out.println();
   }
 }

您的代码行为不符合预期，或者您不明白原因！



有一个几乎通用的解决方案：一步一步地在调试器上运行你的代码，检查变量。

调试器在这里向你展示你的代码正在做什么，你的任务是与它应该做什么进行比较。

调试器中没有魔法，它不知道你的代码应该做什么，它不是找到错误，它只是通过向您展示正在发生的事情来帮助您。当代码没有达到预期的效果时，你就接近了一个错误。

要查看你的代码在做什么：只需设置断点并查看代码是否正常运行，调试器允许你执行第1行第1行，并在执行时检查变量。

调试器只显示你的代码正在做什么，你的任务是与它应该做什么进行比较。

Your code do not behave the way you expect, or you don't understand why !

There is an almost universal solution: Run your code on debugger step by step, inspect variables.
The debugger is here to show you what your code is doing and your task is to compare with what it should do.
There is no magic in the debugger, it don't know what your code is supposed to do, it don't find bugs, it just help you to by showing you what is going on. When the code don't do what is expected, you are close to a bug.
To see what your code is doing: Just set a breakpoint and see your code performing, the debugger allow you to execute lines 1 by 1 and to inspect variables as it execute.

您必须编码

System.out.print("x");

if(column == 10){
  System.out.print("\n");//print newline
