Question:


What is the difference between the two methods, 
nextToken() and hasMoreTokens() 
of StringTokenizer class?

Accepted Answer

Answer:

1. nextToken()


The method:



nextToken()



is used to return the next token (word/string part) 
from the StringTokenizer object.



After returning a token, the tokenizer automatically moves 
to the next token.


Example:


StringTokenizer st = new StringTokenizer("Java is easy");

System.out.println(st.nextToken());



Output:



Java




2. hasMoreTokens()


The method:



hasMoreTokens()



checks whether more tokens are available or not.



It returns:




    
        true → if tokens are still available
    

    
        false → if no tokens remain
    



Example:


while(st.hasMoreTokens())
{
    System.out.println(st.nextToken());
}



This loop continues until all tokens are processed.




Difference Between the Methods:


nextToken()      → Returns next token

hasMoreTokens()  → Checks whether more tokens exist




Conclusion:



    
        nextToken() extracts tokens one by one.
    

    
        hasMoreTokens() is used for checking availability of tokens.
    

    
        Both methods are commonly used together in loops.
