Tips to improve this program

The output of this program is correct and as expected. It is actually a metric of multiplication.

Please advice me regarding code practices, maintability, readability, efficiency etc

package cattledrive;

public class Times {
      public static void main(String[] args) {
            for(int i = 0; i < 11; i++){
                  for(int j = 0; j < 11; j++){
                        if(i == 0){
                              if(j == 0){
                                    System.out.format("%4s" , " ");
                                    continue;
                              }
                              else{
                                    System.out.format("%4d" , j - 1);
                                    continue;
                              }
                        }
                        else{
                              if(j == 0){
                                    System.out.format("%4d", i - 1);
                                    continue;
                              }
                        }
                        
                     System.out.format("%4d" , (i - 1)*(j - 1));
                  }
                  System.out.println();
            }
      }
