            if(intArr[i] == elem){
                // shifting elements
                for(int j = i; j < intArr.length - 1; j++){
                    intArr[j] = intArr[j+1];
                }
                break;
            }
        }
      
        System.out.println("Elements -- " );
        for(int i = 0; i < intArr.length - 1; i++){
            System.out.print(" " + intArr[i]);
        }                
    }
