title: How to return to a specific line of code in java
body: <p>OK so this is my first post here. (Be kind to me :)) I'm like two weeks old to java and wanted to create an app that can do the jobs of a total, average and average grader.
  My question here is. How can I return to a specific line of code after one operation has ended
  Eg: I want the code to runString menu1="Input the number of the operation you desire "; after the total or average has been found.
  Thanks in advance  </p>
  
  <pre><code>import java.util.Scanner;
  public class grader
  {
      public static void main (String args[])
      {
      Scanner input=new Scanner(System.in);
      System.out.println ("Input your Chemistry marks");
      float a= input.nextFloat();
  
      System.out.println ("Input your Biology marks");
      float b= input.nextFloat();
  
      System.out.println ("Input your Physics marks");
      float c= input.nextFloat();
  
      String menu1="Input the number of the operation you desire ";
      String op1="1. Total ";
      String op2="2. Average ";
      String op3="3. Grade ";
      String op4="4. Exit ";
      System.out.println (menu1+op1+op2+op3+op4);
  
      Scanner menuselect=new Scanner(System.in);
      int option= input.nextInt();
  
              float tot=(a+b+c);
              float avg=((a+b+c)/3);
      if (option==1)
          System.out.println ("Your total is "+tot);
  
      else if (option==2)
          System.out.println ("Your average is "+avg);
  
      else if (option==3)
          if (avg&lt;0.0)
              System.out.println ("Please input proper data");
          else if (avg&lt;=49.9)
              System.out.println ("Fail");
          else if (avg&lt;=69.9)
              System.out.println ("Pass");
          else if (avg&lt;=100.0)
              System.out.println ("Excellent");
          else 
              System.out.println ("Please input proper data");
      }
  }
