One of the actions the java compiler does, when it compiles your source code is to "parse" your .java file and create tokens that match the java grammar. When you fail to write the source code properly ( for instance forget to add a;at the end of a statement ), it is the parser...
They both convert a String to a double value but wherease the parseDouble() method returns the primitive double value, the valueOf() method further converts the primitive double to a Double wrapper class object which contains the primitive double value. The conversion from String...

In addition, there are other types of parsers, including the following: Recursive descent parsers.Recursive descent parsers backtrack after each decision point to double-check accuracy. Recursive descent parsers use top-down parsing. Earley parsers.These parse allcontext-free grammars, unlike LL and ...
