Thread: Error using printf function across classes

Hi I am just but a beginner in java programming, I am trying to run a simple program that accesses multiple methods from another class. One of my methods has a String return type.
In the next method I proceed to use the printf function to output the string returned in the previous method but then when i ran my program the first time there were errors and now when I try to run again the class with the main function does not show up in the list of resources to save.
When I hover the cursor on the red cross that highlights an error on a line of code, it says: Multiple markers at this line
- The method printf(String, Object[]) in the type PrintStream is not
applicable for the arguments (String, String)
- The method printf(String, Object[]) in the type PrintStream is not
applicable for the arguments (String, String)
How can I correct this? Thanks in advance.

it would be better it you post of your code.

Check java version you are using, it is possible that you have Java compiler compliance level 1.4.
