有没有办法在Java（Android）中将布尔数组打印为（0,1）

Question

I want to print boolean array as 0,1 in Java(Android)

Now I print boolean[][] like this

Arrays.deepToString(area.paints)

Result Sample

[[true, false, true, false], [true, true, false, false]]

I want print like this

[[1, 0, 1, 0],[1, 1, 0, 0]]

my boolean[][] is too big to check all values and return 0,1

I need fastest method.

If you are just looking to print the array, why don't you just utilize String.replace() :

boolean arr[][] = {{true, false, true, false}, {true, true, false, false}};
System.out.println(Arrays.deepToString(arr).replace("true", "1").replace("false", "0"));

This will give you the output

[[1, 0, 1, 0], [1, 1, 0, 0]]
