Module 2 --Interview question

Control Flow Statement :

In Java, control flow statements determine the order in which instructions are executed in a program.

There are three main types of control flow statements in Java:
    Conditional (Decision-Making) Statements :
        if statement :
            These statements execute certain blocks of code only if a condition is true.
        else statement :
            Executes one block if the condition is true, otherwise executes the else block.
        if-else-if ladder :
            Used to check multiple conditions.
        switch statement :
            The switch case is used for decision-making when we need to execute one block of code out of many options based on a single value.



    Looping (Iteration) Statements :
        These statements repeat a block of code until a condition is false.
        for loop :
            The for loop is used when we need to repeat a block of code multiple times.
        while loop :
            The while loop is used when we need to repeat a block of code multiple times.
        do-while loop :
            Executes the loop at least once, then checks the condition.




    Jump Statements :
        Used to change the normal flow of the program.
        break :
            Exits from the loop or switch immediately.
        continue :
            Skips the current iteration and moves to the next iteration.

Switch Case :

The switch case is used for decision-making when we need to execute one block of code out of many options based on a single value.

Switch case supported these data types like int,char,byte,short in java 1.0 version.

In java 7th version, switch case supported String data types also.

The default is a special case block that executes if none of the case values match the given expression.
