Java JButton的二维数组问题
我需要把数字(2d数组)放在JButton的左上角。但是,我得到的数字结果顺序错误(颠倒),与数组topLeftNum顺序不同。如何使号码以相同的顺序显示?请帮我解决我的问题。谢谢Java JButton的二维数组问题,java,arrays,2d,jbutton,Java,Arrays,2d,Jbutton,我需要把数字(2d数组)放在JButton的左上角。但是,我得到的数字结果顺序错误(颠倒),与数组topLeftNum顺序不同。如何使号码以相同的顺序显示?请帮我解决我的问题。谢谢 final int ROWS = 12; final int COLS = 12; final static int topLeftNum[][]= { {-1, 1, 0, 2, 0, 0, 3, -1, 4, 0, 5, 0}, {6, 0, 0, 0, -1, -1, 0, -1, -1,
