Quick Recall

• Java consists of three conditional control structures.
• A selection statement transfers a program control to a location depending on the result of the
conditional expression.
• If control structure can be considered as bidirectional branching.
• If Else If ladder is used to check multiple conditions in a program.
• The Switch statement works as a jumping statement where the control is transferred to a specifi c
case as per the given switch value.
• Looping is a process of executing a block of statements again and again.
• For loop is used when a group of statements is to be executed a specifi c number of times.

• While loop statement in Java programming language repeatedly executes a target statement
as long as a given condition is true.

• Do While loop is similar to the While loop, except that Do While loop is guaranteed to execute
at least one time.
