--------------------------------------------
i) Java Program Example

//It is a Java Program Example to Understand the Java Syntax as well as Program Structure
package javaExamples;

public degree SampleProgram {
//Create a Method amongst Parameters as well as returning value, Access the method yesteryear invoking the object
public int add(int a, int b){
int effect = a+b;
return result;
}
//Create a Method amongst No Parameters as well as Reruns Nothing, Access the method yesteryear invoking the object   
public void comparison(){
int a=100, b=50;
if (a > b){
System.out.println("A is a Big Number");
}
else
{
System.out.println("B is a Big Number");   
}
}
//Create a Method amongst Parameters, returning a value as well as access the method without Object
public static int sub(int a, int b){
int effect = a -b;
return result;
}
//Create a Method amongst No Parameters, Returns Nothing as well as access the method without Object
public static void comparison2(){
int a=100, b=500;
if (a > b){
System.out.println("A is a Big Number");
}
else
{
System.out.println("B is a Big Number");   
}
}

public static void main(String[] args) {
int a; //Variable Declaration
a=10; //Initialization
int b=20; //Variable Declaration as well as Initialization
double c = 1.234;
int d, e, f; //Declaration of Multiple Variables
int g =30, h=40, k=50;//Declaration of Multiple Variables as well as Initialization

int l = a + b;
System.out.println("Addition of a, b is: "+l);//30
System.out.println(k);//50
k=123;
System.out.println(k);//123

final int abc = 100;//Constant Declaration
System.out.println(abc);//100

if (a > b){
System.out.println("A is a Big Number");
}
else {
System.out.println("B is a Big Number");
}
String mytool = "Selenium Testing";
System.out.println(mytool);

char degree = 'A';

switch (grade){ //Decide amid several Alternates

case 'A':
System.out.println("Excellent");
break;

case 'B':
System.out.println("Good");
break;

case 'C':
System.out.println("Better");
break;

default:
System.out.println("Invalid Grade");
}

for (int i = 1; i <= 10; i++){ //Repetitive Execution
if (i != 7){
System.out.println(i);   
}
}

int j=5; //Display i to five Numbers using piece loop
while(j>=1){
System.out.println(j);
j--;
}

int thousand =20;
do
{
System.out.println(m);
m++;
} piece (m<=6);

String [] tools = {"Selenium","UFT", "RFT", "SilkTest"};
System.out.println(tools.length);

for (String xyz: tools){
System.out.println(xyz);   
}

//Create Object
SampleProgram obj = novel SampleProgram();
int res = obj.add(123, 321);
System.out.println(res);

System.out.println(obj.add(123, 321));

obj.comparison();

//Access Static methods using Class Name

int res2 = SampleProgram.sub(200, 123);
System.out.println(res2);

System.out.println(SampleProgram.sub(200, 123));

SampleProgram.comparison2();

}
}

ii) Comments inwards Java

Comments are English linguistic communication words used for Code Documentation.

1) Purpose of Comments
 
    a) To brand the Code Readable
    b) To brand the Code disable from Execution.

2) Comments Syntax inwards Java
a) Use // for Single Comment

b) Use /*.............
.....................
.....................
..................*/ for multiple delineate of piece of employment comment

Or
Comment Multiple Lines

(Eclipse IDE)
Select Statements/Steps
Source Menu -> Add Block Comment

Uncomment

(Eclipse IDE)
Select Comment block
Source Menu -> Remove Block Comment
---------------------------------------------------
3) Example:

public degree Sample2 {

public static void main(String[] args) {
int a, b; //Variables Declaration
a =10; b=20;
int c = a+b;
//Display the Addition value of a as well as b
System.out.println("Addition of a, b is: "+c);
System.out.println("");

/*if (a > b) {
System.out.println("A is a Big Number");   
}
else
{
System.out.println("B is a Big Number")    ;
}*/

}
}
------------------------------------------------
4) Usage of Comments inwards Test Automation
a) To Write Test instance header

b) To Write Method header

c) To Explain Complex Logic
