Lambda Expressions in Java

Lambda Expressions: It is a anonymous(nameless) function. It does not has method name, method return type nor modifiers

           General Method:

                 public void m1(){
                          System.out.println("Hello world");
                 }
           Converting above method into lamda expression:
           for that we use '->' symbol
           no method name,no return type and no modifiers
           () -> {System.out.println("Hello world");}
