[JAVA] converter

 / Published in: Java
 

this programming convert number and key word to a sentence. however, it still has a problem about if statement, when i add else after the if statement every time it executes so every result became in the else statement one. [UPDATED] Now it runs, I added another huge contents of if statement.
