Java Array problem

How do I make a sudoku like program in java(not the game) just to creat an array of 3x3 dimensions that fills the rows and columns with random numbers. IMPORTANT: the numbers must no repeat itself.

hi ‚ÄĘ WTF [‚ÄĘ_‚ÄĘ] ‚ÄĘ here is how you‚Äôd make a 3x3 array.. int[ ][ ][] sample = { {1, 2, 3}, {4, 5, 6}, {7,8,9}}; then you‚Äôd just need to use the random function in java java.util.Random Random random = new Random(); return random.ints(min, max) .findFirst() .getAsInt();

Maybe you could make an if statement to test if the next number matches any of the other numbers? Example: After telling it to pick a number, then put, if(!sample[2] == sample[1]){ input code } else [ pick new number } I don't know, i'm learning as well, but it works in my mind lol
