Switch Statement

-





Switch statements are also used when we need our program to make a certain decision based on a condition and then execute accordingly.

Syntax:

switch(expression)
{
    case value-1:
    statements which will be executed if the value obtained by evaluating the expression is value-1

               break;

    case value-2:
    statements which will be executed if the value obtained by evaluating the expression is value-2

               break;
    ...
    ...
    ...
    case value-n:
     statements which will be executed if the value obtained by evaluating the expression is value-n

               break;

     default :
     statements which will be executed if the value is not matching with any of the above values

               break;
    }
    //statements after the switch block

Example:

/*
 * File Name : SwitchStatementDemo1.java
 */
public class SwitchStatementDemo1
{

    public static void main(String args[])
    {

        int choice = 2;

        switch (choice)
        {
        case 1:
            System. out .println( "Bank Menu" );
            break ;

        case 2:
            System. out .println( "Loan Menu" );
            break ;

        case 3:
            System. out .println( "Credit Card Menu" );
            break ;

        default :
            System. out .println( "No Match Found" );
        break ;

        }
    }
}

Output:
Loan Menu
Here the program displayed the message “Loan Menu” because the variable “choice” is assigned as 2.

Naming Conventions

Image
A naming convention is a rule to follow as you decide what to name your identifiers (e.g. class, package, variable, method, etc..). Different Java programmers can have different styles and approaches to the way they program. By using standard Java naming conventions they make their code easier to read for themselves and for other programmers. Cases in Java Naming Convention: Using the right letter case is the key to following a naming convention: Lowercase is where all the letters in a word are written without any capitalization (e.g., while, if, mypackage). Uppercase is where all the letters in a word are written in capitals. When there are more than two words in the name use underscores to separate them (e.g., MAX_HOURS, FIRST_DAY_OF_WEEK). CamelCase (also known as Upper CamelCase) is where each new word begins with a capital letter (e.g., CamelCase, CustomerAccount, PlayingCard). Mixed case (also known as Lower CamelCase) is the same as CamelCase except the fir...

Reference Data Types

-
Reference variables are created using defined constructors of the classes. They are used to access objects. These variables are declared to be of a specific type that cannot be changed. For example, Employee, Puppy etc. Class objects, and various type of array variables come under reference data type. Default value of any reference variable is null. A reference variable can be used to refer to any object of the declared type or any compatible type. Example: Animal animal = new Animal("giraffe");

Nested if..else Statement

-
You can combine multiple if / if-else /if-else-if ladders when a series of decisions are involved. So you can make sure that your program executes certain instructions when a series of conditions are met. Syntax: if(Boolean_expression 1) { //Executes when the Boolean expression 1 is true; } if(Boolean_expression 2) { //Executes when the Boolean expression 2 is true } //Statements which will be executed always      Example: public class Test {    public static void main(String args[])    {        int x = 30;        int y = 10;        if( x == 30 )        {            if( y == 10 )            {            System.out.prin...
