Learn how to use if-else statements in Java to control the flow of your program. Understand syntax, examples, and best practices.
Directly manipulating threads this way is fine for simple examples, but with concurrent programming, such code can quickly become error-prone, especially when several threads need to cooperate to perform a larger task. In such cases, their control flow needs to be coordinated. For example, the ...
Java if...else Statement Java continue StatementWhile working with loops, sometimes you might want to skip some statements or terminate the loop. In such cases, break and continue statements are used. To learn about the break statement, visit Java break. Here, we will learn about the continue...
