Parameters, Local Variables, and Overloading

19. Overloaded println()



Answer:
Yes. The names of the formal parameters do not have to be unique.






Overloaded println()



    





    

    

    

    











    







    
We have already been using overloading. The println() method (for example) has several overloaded versions:

    
    
        
      
            
        
                
      • println( )
        • 
                
      • println( boolean x )
        • 
                
      • println( char x )
        • 
                
      • println( double x )
        • 
                
      • println( int x )
        • 
                
      • println( String x )
        • 
                
      • ... others
        • 
            
      
        
    
    

    
Which version of println() gets called depends on the argument.




Question 19:
Which version of println() is called in the following:
    System.out.println( "The result is: " + 34 );
