However, in computer programming, the statement to be executed next may not necessarily be located in the next line of code. This is referred to as transfer of program control. In the following lessons, you will gain an understanding of control structures and statements in the Java programming...
In a given block, the program is executed sequentially one statement at a time starting from the first statement at the top and proceeding toward the bottom. This scheme, without any additional flow logic, will execute each statement precisely once. However, if a programming language is to ...
