Java Exceptions

• All RuntimeExceptions are unchecked exceptions rest of them are checked exceptions
  
• Always use try-with-resource. In order to use objects  should implement AutoClosable
  
• Exceptions are very slowly. Code running inside try-catch is performing slowly. If you have chance just use simple test (like if(!s.empty) s.pop() ) rather then guarded section
  
• Throw early, catch late
