since its introduction in java 8, the stream api has become a staple of java development. the basic operations like iterating, filtering, mapping sequences of elements are deceptively simple to use. but these can also be overused and fall into some common pitfalls. to get a better understandi...
Java If-else Theif-else statementin Java is the most basic of all theflow control statements. Anif-elsestatement tells the program to execute a certain block only if a particular test evaluates totrue, else execute the alternate block if the condition isfalse. Theifandelseare reservedkeywords...
Theifstatement, along with its optionalelse, is used to build an “if conditional” expression. It says: If something is true, then do this. Theifstatement is called aconditional expressionbecause it tests for a specific condition. The following rules apply when usingif…elsestatements: If the...
This way the class under test is in a controlled environment where you can test its own business logic with nothing else in the way. There are times, however, when you should not use mocking during testing. For these cases, you need Java integration testing. Read on to learn: Table of...
loop’s function by using a labeled break statement. This can be useful when you need to stop the loop based on aconditionoutside of the loop, such as a user input or asystemevent. In this blog post, we will explore how to use labeled break statements in Java and provide code ...
In this blog, you will learn what enumeration is and its implementation of code in the C programming language. This blog will guide you on when and how to use enumeration in C, including implementation in switch statements and flags. Further, we will be exploring the differences between enum...
We can verify the log statements and insert queries in the console logs because we have enabled the trace logging for H2 database. You must disable it in your production environment. Do not forget to use thedatabase connection pooling, else the logging will be very costly in terms of perfor...
In many cases switch statement provides a cleaner way to handle complex decision logic. Let’s see an example to understand difference between if-else and switch statements. Example : int x=3; if(x==1){ System.out.println("x equals 1"); ...
