Similar Language FunctionsSimilar Language Functions

Although each language has its own syntax, their functional equivalence is essentially the same.

Syntax ExampleSyntax Example

VB.NET:if x > 1 thenDoSomething()

end if

JAVA / C#:if (x>1) {DoSomething();

}

For a programmer, language choice is more aesthetic than functional.

The real difference is in the libraries.
