This video talks about control structures, which can be thought of as ways to modify the standard flow of code. The concept of control structures are the same in any programming language, but this basic java tutorial video will show you the syntax for Java
if (then) statements
A nested if is an if statement that is the target of another if or else.
The switch statement provides a beter alternative than a large series if-else-if statements
Break (terminates a statement sequence in a swithc statement, exit a loop, ”civilized” for of goto.
Continue (in all three loops, any intermediate code is bypassed.)
Return ( is used to explicitly return from a method.)
