Learn in an expression what do lvalue and rvalue mean.

What is rvalue and lvalue in java.

L value may appear as either left hand or right hand side of an assignment operator. But in c this definition has changed and become more interesting. Array names and constant identifiers are non modifiable l values and variables objects are modifiable l values. The only mention of them in the language spec is here where it says a variable 4 12 in c this would be called an lvalue.

An lvalue locator value represents an object that occupies some identifiable location in memory i e. They say that literals constants like 2 a hello 4 5 etc are r values. Left of assignment operator is lvalue and right ofassignment operator is rvalue. Every expression is either an lvalue or an rvalue so an rvalue is an expression that does not represent an object occupying some identifiable location in memory.

One could also say that an rvalue is any expression that is not an lvalue. An lvalue is an expression variable constant etc which appears at left hand side of an assignment operator. Java doesn t really have a concept of lvalues and rvalues. Result is an lvalue.

Every expression is either an lvalue or an rvalue so an rvalue is an expression that does not represent an object occupying some identifiable location in memory.
