Java Lambda Expressions - javatpoint The => token is supported in two forms: as the lambda operator and as a separator of a member name and the member implementation in an expression body definition.. Lambda operator. :, also known as the ternary conditional operator, evaluates a Boolean expression and returns the result of one of the two expressions, depending on whether the Boolean expression evaluates to true or false, as the following example shows: C#. The following code example uses the function from the previous example, and adds an example of a lambda expression that uses the C++ Standard Library algorithm generate_n. Now we can break those limitations and see how to add multiple if statements in the lambda function. Here is the syntax for using lambda expressions in C#. In the short term, you might get by with something much simpler: a list of primitive expressions and a bool flag to say whether they should be combined with && or ||. A lambda can introduce new variables in its body (in C++14), and it can also access, or capture, variables from the surrounding scope. Asking for help, clarification, or responding to other answers.
