Maybe Java got a little cryptic in version 8 because of the introduction of lambdaNov 15, 2013 · The :: operator was introduced in Java 8 for method references. A method reference is the shorthand syntax for a lambda expression that executes just one method. Here's the general syntax of a method reference: Object :: methodName. We know that we can use lambda expressions instead of using an anonymous class. Using the Not Equals Operator in Java. The most basic way to use the not equals operator is to check for equality between two variables. The program has two int variables, num1 and num2. Here, num1 contains the value 123, and the num2 variable has 321. We create an if condition to check if the variables match or not.The if-then Statement. The if-then statement is the most basic of all the control flow statements. It tells your program to execute a certain section of code only if a particular test evaluates to true.For example, the Bicycle class could allow the brakes to decrease the bicycle's speed only if the bicycle is already in motion.

You have seen an example of arrays already, in the main method of the "Hello World!" application. Example explained. Statement 1 sets a variable before the loop starts (int i = 0). Statement 2 defines the condition for the loop to run (i must be less than 5). If the condition is true, the loop will start over again, if it is false, the loop will end. Statement 3 increases a value (i++) each time the code block in the loop has been executed.When comparing C# vs. Java, it’s important to look beyond syntax and consider the semantics – the behavior and meaning of the constructs in each language.
