Scope of a variable denotes span of a variable. The scope of a local variable is within that method i.e. when we create a variable with in a method, it cannot be accessed outside that method. Example If you observe the following example here, we have created a variable named num in the main method and, trying to access it in another method (demo). public class SampleTest { String str = "sampleString"; public static void main(String args[]){ int num = 334; ...

SAPUI5 allows the developer to use their own static HTML elements with the use of UI5 controls in certain areas. It is not closed framework and allows you to use a sap.ui.core.HTML control to write any amount of plain HTML within an area rendered by UI5 so it allows you to easily mix HTML and UI5 controls.HTML created by UI5 controls, however, is created dynamically, but that's how many JavaScript UI libraries work when providing higher-level UI elements that would be hard to write in static HTML.You can refer to below link of SAPUI5 which tells more about HTML SAPUI5 ...

No, local variables do not have default values. Once we create a local variable we must initialize it before using it. Since the local variables in Java are stored in stack in JVM there is a chance of getting the previous value as default value. Therefore, In Java default values for local variables are not allowed. Example public class Sample { public static void main(String args[] ){ int data; System.out.println(data); } } Error C:\Sample>javac Sample.java Sample.java:4: error: variable data might not have been initialized System.out.println(data); ^ 1 error

The final modifier for finalizing the implementations of classes, methods, and variables. The main purpose of using a class being declared as final is to prevent the class from being subclassed. If a class is marked as final then no class can inherit any feature from the final class. You cannot extend a final class. If you try it gives you a compile time error. Example final class Super { private int data = 30; } public class Sub extends Super{ } Output C:\Sample>javac Sub.java Sub.java:7: error: cannot inherit from final Super public class Sub extends Super{ ^ 1 error
