Java Loops and Introduction to Arrays - Post Class - Pattern making

Q16-Given an integer n, your task is to print the pattern as shown in example:-
For n=5, the pattern is:
1
1 2 1
1 2 3 2 1
1 2 3 4 3 2 1
1 2 3 4 5 4 3 2 1
1 2 3 4 3 2 1
1 2 3 2 1
1 2 1
1
Ans-public static void pattern_making(int n){
           for(int i=1; i<=n; i++){
               for(int j=1; j<=i; j++){
                   System.out.print(j+" ");
               }
               for(int k=i-1; k>0; k--){
                   System.out.print(k+" ");
               }
               System.out.println();
           }
           for(int i=n-1; i>0; i--){
               for(int j=1; j<i; j++){
                   System.out.print(j+" ");
               }
               for(int k=i; k>0; k--){
                   System.out.print(k+" ");
               }
               System.out.println();
           }
}
