如果存在更多的1，为什么1s在整行中打印 [英] Why does 1s print in the entire row if more that one is present

问题描述

我正在制作一个程序，给出ax和ay值java将在相应的坐标位置打印到屏幕a 1。但是当存在超过11时，它会打印整行8为1而不是有些为0

I am making a program that given a x and a y value java will print to the screen a 1 in that corresponding coordinate position.But when more than 1 "1" is present it prints the entire row of 8 as 1 instead of some as 0

我尝试了什么：



我试过更换&到|并改变一些循环值，但这些都没有效果。

What I have tried:

I have tried changing the & to a | and changing some of the loop values and neither of those have worked.

推荐答案

尝试

Try

if(queen[i][0]==j && queen[i][1]==i){

请参阅bitwise和logican运算符之间的区别：
