This post shows what does “Cannot make a static reference to the non-static method or a non-static field” error means and how to fix that error. static reference to the non-static field or method error In order to understand why this error crops up you’ll have to understand the difference between…
Static block in Java is used to initialize the static variables (also known as class variables). To initialize instance variables there are constructors, where error handling or other logic can be used. To provide the same capability for class variables, there are static initialization blocks in Java. Syntax of Java…
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 methods 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…
In the post conditional operators in Java we talked about the Conditional-AND and Conditional-OR operators, here we’ll talk about another conditional operator known as ternary operator in Java (?:). Ternary operator uses three operands thus the name ternary operator and it can be used in place of if-else statement or…
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…
