1. Program(== method Program): Class Hello { Public static void main(String args[])throws Exception{ Int a=112; Int b =112; System.out.println(a==b); Int a1 =113; Int b1=113; System.out.println(a1=b1); } } Output: True 113 2. Program(Static Method Program): public class StaticClass { public static void brahmi(){ System.out.println("I am Static Method"); } public static void main(String args[]) { StaticClass bb = null; bb.brahmi(); //Static variable called by class name .so no need to bother about If we initialize ‘null’ value to the static method (but if it is instance method, throw error) } } Output: I am Static Method 3. Program (overloading program): public class overLoading { public static void brahmi(int a){ System.out.println("First Overload Method"); } public static void brahmi(Integer a){ System.out.println("Second Overload Method"); } public static void main(String args[]) { biswa bb = null; bb.brahmi(1); bb.brahmi((Integer)1); } } Output: First Overload Method Second Overload Method 4. Program (interface program): interface brahmi { public abstract static brahmi(int a){ System.out.println("First Method"); } public static brahmi(Integer a){ System.out.println("Second Method"); } int a,b; } class M implements brahmi{ system.out.println(a); } Output: Compile time Error because Interface can't have static methods, main method or constructor Interface can have only abstract methods Interface can't provide the implementation of abstract class. The blank final field a may not have been initialized( If you initialize values to the a, b variables, default it will convert final variables because Interface has only static and final variables & that variables data we may not change in sub classes) 5. What is primitive data Type and Object 6. Compile binding vs Runtime binding difference 7. Handle windows popups using selenium Webdriver (A). package com.pack; import java.util.Set; import org.openqa.selenium.WebDriver; import org.openqa.selenium.firefox.FirefoxDriver; import org.testng.Assert; import org.testng.annotations.Test; public class WindowExamples { static WebDriver driver; @Test public void test_CloseAllWindowsExceptMainWindow() { driver = new FirefoxDriver(); // It will open Naukri website with multiple windows driver.get("http://www.naukri.com/"); // To get the main window handle String windowTitle= getCurrentWindowTitle(); String mainWindow = getMainWindowHandle(driver); Assert.assertTrue(closeAllOtherWindows(mainWindow)); Assert.assertTrue(windowTitle.contains("Jobs - Recruitment"), "Main window title is not matching"); } public String getMainWindowHandle(WebDriver driver) { return driver.getWindowHandle(); } public String getCurrentWindowTitle() { String windowTitle = driver.getTitle(); return windowTitle; } //To close all the other windows except the main window. public static boolean closeAllOtherWindows(String openWindowHandle) { Set<String> allWindowHandles = driver.getWindowHandles(); for (String currentWindowHandle : allWindowHandles) { if (!currentWindowHandle.equals(openWindowHandle)) { driver.switchTo().window(currentWindowHandle); driver.close(); } } driver.switchTo().window(openWindowHandle); if (driver.getWindowHandles().size() == 1) return true; else return false; } } 8.
