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();
            }
      }

With such a simple program, there is not much you can do to improve readability or maintainability except perhaps:

1) Add some comments to describe what you are doing
2) Use more descriptive variable names than i and j

At best you can remove the else clauses out of the program because they are redundant, and follows the guidelines provided by mrjoltcola
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;
                    }
                    System.out.format("%4d", j - 1);
                    continue;
                }
                if (j == 0)
                {
                    System.out.format("%4d", i - 1);
                    continue;
                }
 
                System.out.format("%4d", (i - 1) * (j - 1));
            }
            System.out.println();
        }
    }
