         int num3 = 40
         int tot;
         tot = num1 + num2 + num3 ;
       system.out.printIn("total of + num1 +"and" + num2 +"and"+num3+"is"+tot);
    }
} 
  
 control flow statements 
program to display table of 3 using for loop

                  system.out.printIn("3*"+i+"="+j);
                }

Answer 2

/* to  Write a program to Concatenate  string using for Loop
Example:          
Input - 4         
 Output - 1 2 3 4 */
class Join{     
 public static void main(String args[]){      
int num = Integer.parseInt(args[0]);     
 String result = " ";     
 for(int i=1;i<=num;i++){          
 result = result + i + " ";     
 }
  System.out.println(result); 
 }
