make 2D array more less in Java-CodePudding

I have a Java code with 2d arrays and i want to rewrite this code to look like it has less code than i wrote before.

The main task of my code is to have cubes in 1.

Is there any ideas how to fix it?

My Data:

2 0 0 1 1 0 0 0
0 0 1 0 0 1 0 0
0 0 0 0 0 0 0 0
1 0 1 0 0 1 0 1
1 0 0 0 0 0 0 1
0 0 0 0 0 0 0 0
0 0 1 0 0 1 0 0
0 0 0 1 1 0 0 0

My Code:

 for(int i = 0; i < map.length; i  ) {
            for(int j = 0; j < map.length; j  ) {
                if(map[i][j] == map[0][3]) {
                    gc.fillRect(i, j, 1, 1);
                }
                if(map[i][j] == map[0][4]) {
                    gc.fillRect(i, j, 1, 1);
                }
                if(map[i][j] == map[1][2]) {
                    gc.fillRect(i, j, 1, 1);
                }
                if(map[i][j] == map[1][5]) {
                    gc.fillRect(i, j, 1, 1);
                }
                if(map[i][j] == map[3][0]) {
                    gc.fillRect(i, j, 1, 1);
                }
                if(map[i][j] == map[3][2]) {
                    gc.fillRect(i, j, 1, 1);
                }
                if(map[i][j] == map[3][5]) {
                    gc.fillRect(i, j, 1, 1);
                }
                if(map[i][j] == map[3][7]) {
                    gc.fillRect(i, j, 1, 1);
                }
                if(map[i][j] == map[4][7]) {
                    gc.fillRect(i, j, 1, 1);
                }
                if(map[i][j] == map[6][2]) {
                    gc.fillRect(i, j, 1, 1);
                }
                if(map[i][j] == map[6][5]) {
                    gc.fillRect(i, j, 1, 1);
                }
                if(map[i][j] == map[7][3]) {
                    gc.fillRect(i, j, 1, 1);
                }
                if(map[i][j] == map[7][4]) {
                    gc.fillRect(i, j, 1, 1);
                }
    
              
            }
        }

CodePudding user response：

You are compairing every field in your map with every field in your map that equals 1. So you could just check if the value of one field is 1:

    for (int i = 0; i < map.length; i  ) {
        for (int j = 0; j < map[0].length; j  ) {
            if (map[i][j] == 1) {
                gc.fillRect(i, j, 1, 1);
            }
        }
    }
