Learn for and while loops. Learn about certain commands that return a true/false value.

1. for loops. The basic structure is:

       for(counter start; counter stop test; counter increment) {
           body of the loop
     
       } 
   

   Example:

       for(int i=0; i<n ; i++) {
          robot.pickBeeper();
       }
   

2. while loops. Basic structure:

          while(test condition(s)) {
              
              body of the loop
   
          }
   
          The test condition(s) are functions that return true or false
     

   Example:

         while(robot.nextToABeeper()) {
            robot.pickBeeper();
         }
   
         while (!robo1.rightIsClear() && !robo1.nextToABeeper()) {
                  
                commands
                  
         }
   
    
   boolean commands that return true/false.  Some examples:
    
        
        facingEast()
        facingNorth()
        facingSouth()
        facingWest()
        frontIsClear()
        leftIsClear()
        nextToABeeper()
        nextToARobot()
    
    
   if statements
    
        if(boolean statement(s)) {
   
            body of if
      
        } else {
       
            alternative body
        }
   
        The "else" portion is optional
