Passing datasets created by traditional job steps to Java programs, which convert the data to XML. Employing long-running started tasks for Java that periodically query a database to find new work to process. Whereas in the past Java might have been considered slow or too resource intensive, the modern JVMs, with their just-in-time translation JIT to machine code, have excellent performance characteristics for many tasks.

Next Page Dear readers, these Java Interview Questions have been designed especially to get you acquainted with the nature of questions you may encounter during your interview for the subject of Java Programming Language.

Java is a high-level programming language originally developed by Sun Microsystems and released in What are the supported platforms by Java Programming Language? List any five features of Java? How Java enabled High Performance? Java uses Just-In-Time compiler to enable high performance.

Just-In-Time compiler is a program that turns Java bytecode, which is a program that contains instructions that must be interpreted into instructions that can be sent directly to the processor. Why Java is considered dynamic?

It is designed to adapt to an evolving environment. Java write ascii programs can carry extensive amount of run-time information that can be used to verify and resolve accesses to objects on run-time. When Java is compiled, it is not compiled into platform specific machine, rather into platform independent byte code.

This byte code is distributed over the web and interpreted by virtual Machine JVM on whichever platform it is being run. Some Java keywords are import, super, finally, etc. What do you mean by Object? Methods operate on an object's internal state and serve as the primary mechanism for object-to-object communication.

A class is a blue print from which individual objects are created. A class can contain fields and methods to describe the behavior of an object.

What kind of variables a class can consist of?

A class consist of Local variable, instance variables and class variables. What is a Local Variable? Variables defined inside methods, constructors or blocks are called local variables. The variable will be declared and initialized within the method and it will be destroyed when the method has completed.

What is a Instance Variable? Instance variables are variables within a class but outside any method. These variables are instantiated when the class is loaded. What is a Class Variable?

These are variables declared with in a class, outside any method, with the static keyword. What is Singleton class? Singleton class control object creation, limiting the number to one but allowing the flexibility to create more objects if the situation changes.

What do you mean by Constructor? Constructor gets invoked when a new object is created. Every class has a constructor.

If we do not explicitly write a constructor for a class the java compiler builds a default constructor for that class. List the three steps for creating an Object for a class? An Object is first declared, then instantiated and then it is initialized. What is the default value of byte datatype in Java?

Default value of byte datatype is 0.

Java Programs and Examples with Output

What is the default value of float and double datatype in Java? For float its 0. This data type is used to save space in large arrays, mainly in place of integers, since a byte is four times smaller than an int. What is a static variable? Class variables also known as static variables are declared with the static keyword in a class, but outside a method, constructor or a block.

What do you mean by Access Modifier? Java provides access modifiers to set access levels for classes, variables, methods and constructors. A member has package or default accessibility when no accessibility modifier is specified.Java and Selenium are the best automation tools for QA. And these skills are a must for every QA engineer involved in test automation.

Hence, in this post, we’re presenting a set of 10 Java coding questions to help test automation developers during job interviews. A COMPARISON OF MICROSOFT'S C# PROGRAMMING LANGUAGE TO SUN MICROSYSTEMS' JAVA PROGRAMMING LANGUAGE By Dare Obasanjo Introduction.

Jul 13,  · Enum Singletons are new way to implement Singleton pattern in Java by using Enum with just one instance. Though Singleton pattern in Java exists from long time Enum Singletons are relatively new concept and in practice from Java 5 onwards after introduction of Enum as keyword and feature.
