class A { synchronized void m1() { System.out.println("In m1 A"); } void m2() { System.out.println("In m2 A"); } } There are two threads T1 and T2. T1 is accessing m1 method. Will T2 be able to access m2 method on the same instance at the same time?

Now, let's say we are given a list of employee objects listOfEmployees and we need to obtain a list of the names of employees. Here, we will use the map() method of the Stream API that takes a Function as a parameter.

Let's use this method to write the Function functional interface.

Step 3:  Write the implementation similar to a method which takes String as input and returns nothing. Please note that we need to use curly braces {} and a return statement when we want to execute multiple statements.

Step 2 : Put Array Operator

Step 1: Go to the source code functional interface for which you need to write lambda expressions and copy the parameters of its abstract method. For example: Let's say you want to write lambda expression for Consumer.

To write a Predicate:

A Predicate is a single-argument functional interface that returns a boolean value, either true or false. It accepts one argument and yields a result as either true or false.
