String cannot be resolved to a type - Java RAD

My guess is you miss the JRE Runtime Library in your project. But this would cause all the java.* classes to generate this message! Can you post your code so we can see what might be the problem?

try doing :

right-click on your project. ->properites ->java Build Path ->tab Librairies

check if the JRE System Library is there.

i am a beginner. i am using Eclipse and got stuck at the Hello World code. Got same error description and also error stating can't resolve 'system'.

After staying frustrated for few hours, as I checked JRE library path and stuff, I just Capitalized 'S' of 'string' and 'system'.. and bang.. problem solved. I hope this helps.
