How can we write a multiline lambda expression in Java?
Lambda expression is an anonymous method that has used to provide an implementation of a method defined by a functional interface. In Java 8, it is also possible for the body of a lambda expression to be a complex expression or statement, which means a lambda expression consisting of more than one line. In that case, the semicolons are necessary. If the lambda expression returns a result then the return keyword is also required.
Syntax
([comma seperated argument-list]) -> { multiline statements }Example
interface Employee {
String displayName(String s);
}
public class MultilineLambdaTest {
public static void main(String[] s) {
Employee emp = (x) -> { // Lambda Expression with multiple lines
x = "Jai " + x;
System.out.println(x);
return x;
};
emp.displayName("Adithya");
}
}Output
Jai Adithya
