Sometimes you may need to continue to the next iteration with in the loop with out executing the statements or you may need to terminate the loop altogether. For these two scenarios Java provides two control statements- continue and break. In this post we’ll go through Java break statement in…
Switch statement is Java’s selection statement which can have a number of possible execution paths. Another selection statement if-else-if ladder in Java also executes one of the code block based on the evaluation of the condition, switch-case in Java provides an easier and more readable alternative to do the same…
In Java programming language there are two selection statements if-else and switch statement to control the execution flow. This post talks about if and if-else statements in detail with examples. Java if-else statement Java if-else statement is used to evaluate a condition and take the execution path based on whether…
Loop in any programming language is used to repeatedly execute a block of code until a condition to terminate the loop is satisfied. In Java there are three types of loops- while loop, do-while loop and for loop. In this post we’ll see how to use for loop in Java.…
while loop in Java repeatedly executes a block of statement while the given condition is true. Syntax of the while loop in Java is as follows- while (condition) { // body } Block of code that is executed with in a loop is enclosed in curly braces. If only a…
A do-while loop in Java repeatedly executes a block of statement while the given condition is true. Java do-while loop is similar to while loop except one difference that the condition in the do-while loop is evaluated at the bottom rather than at the top (as is the case with…
In Java 8 two new features were added to the interfaces in Java- Default methods and static methods. Java 9 added one more capability of adding private methods to the interfaces in Java. Interface private method in Java Private methods in Java interfaces can be defined using private modifier the…
The Java Shell or JShell is an interactive command line tool for learning the Java programming language and to test Java code. JShell is a Read-Evaluate-Print Loop (REPL), which evaluates declarations, statements, and expressions as they are typed and immediately shows the results. This way you don’t need to write…
In this post we’ll discuss a feature called local variable type inference which is included in Java 10. A new reserved type name “var” is added in Java to define and initialize local variables. Note that var is not a keyword, it’s a reserved type name. So your existing variable…
ThreadPoolExecutor in Java is used to execute each submitted task using one of possibly several pooled threads. When an instance of ThreadPoolExecutor is created a thread pool is also created and one of the thread from this pool of threads is used to execute tasks. Java ThreadPoolExecutor ThreadPoolExecutor class is…
