Java is an object-oriented programming language. It was developed by James Gosling and his team including Mike
Sheridan and Patrick Naughton, at Sun Microsystems in 1995. It is very useful in developing apps, website contents, game
and software. It works on the principle of WORA.
1. Give one example of OOP language apart from JAVA.
2. Name the persons who developed Java.
3. Name the software firm from where java was developed.
4. What is the full form of WORA?
5. What are the places where Java is useful?
F. Assertion and Reasoning based questions.
The following questions consist of two statements – Assertion (A) and Reason (R). Answer these questions by selecting
the appropriate option given below:
(a) Both A and R are true, and R is the correct explanation of A.
(b) Both A and R are true, but R is not the correct explanation of A.
(c) A is true, but R is false.
(d) A is false, but R is true.
1. Assertion(A): Java was developed in the 1980s by Oracle Corporation.
Reason(R): The original development of Java was led by James Gosling and his team at Sun Microsystems.
2. Assertion(A): BlueJ is an integrated development environment (IDE) designed for teaching object-oriented
programming.
Reason(R): BlueJ allows developers to create and manage large enterprise-level applications with advanced features
like integrated version control and continuous integration tools.
3. Assertion(A): The Java compiler translates Java source code directly into machine code.
Reason(R): The Java interpreter, or Java Virtual Machine (JVM), executes the compiled bytecode, making Java
platform-independent.
