When a class member is defined using static keyword in Java it is associated with the class rather than with the instances of the class. That gives rise to a question can we overload or override static method in Java. This post tries to answer this question. Before that let’s…
Continue statement in Java is used to force the iteration of the loop. As soon as a continue statement is encountered in a loop, remaining statements in the loop that follow the continue statement are not executed and the control jumps to the next iteration of the loop. What happens…
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…
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…
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- Block of code that is executed with in a loop is enclosed with in curly braces. If only a single statement is executed with…
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.…
Difference between equals() method and equality operator “==” in Java is asked quite frequently in beginner level Java interviews. Since both equals() and == operator are used for comparison so it is necessary to know the differences between these two in order to ensure correct usage of one of them…
When you assign a value of one type to a variable of another data type, Java performs type conversion to accommodate the value to different type. This type conversion may happen automatically or you may need an explicit type casting to perform the type conversion. So, both of these terms…
