Answer 1

for(int i = 0; i<matrix.length; i++){
for(int j =0; j<matrix.length; j++){
System.out.print(matrix[i][j] + " ");
}
System.out.println();
}

Explanation: println adds a line break after each number, but print doesn't. So in the inside you only print a number and a space. After the inner loop you println nothing, which pushes the cursor to the next line.
