    Which of the following is an extension of the Java program? - ProProfs

    Which of the following is an extension of the Java program?

    • .txt

    • .doc

    • .class

    • .java

    Correct Answer
    A. .java
    Explanation
    The extension ".java" is the correct answer because it is commonly used to denote a Java program file. In Java, source code files are typically saved with a .java extension. This allows the Java compiler to recognize and process the file as a Java program. The other options (.txt, .doc, .class) are not specific to Java programs and are used for different file types or formats.

    Which of the following application program is required to run java program? - ProProfs

    Which of the following application program is required to run java program?

    • Jdk

    • Dbk

    • SDK

    • None of these

    Correct Answer
    A. Jdk
    Explanation
    The Java Development Kit (jdk) is required to run a Java program. It includes all the necessary tools and libraries needed for compiling, debugging, and executing Java code. The jdk provides the Java Virtual Machine (JVM) which is responsible for running Java programs on different platforms. The other options, dbk and SDK, are not valid choices as they do not refer to the specific program required for running Java programs. Therefore, the correct answer is jdk.

    To convert Java language code into output form, which of the following operation(s) is/are needed? - ProProfs

    To convert Java language code into output form, which of the following operation(s) is/are needed?

    • Interpretation

    • Compilation

    • Both a and b

    • None of the above

    Correct Answer
    A. Both a and b
    Explanation
    To convert Java language code into output form, both interpretation and compilation are needed. Interpretation involves executing the code line by line, while compilation involves translating the code into a machine-readable format. Both processes are necessary to ensure that the code is correctly executed and produces the desired output.

    Is Java language 100% object-oriented? - ProProfs

    Is Java language 100% object-oriented?

    • Yes

    • No

    • Maybe

    • Can't Say

    Correct Answer
    A. No
    Explanation
    Java language is not 100% object-oriented because it supports primitive data types, such as int and boolean, which are not objects. Additionally, Java has static methods and variables that belong to the class rather than an instance of the class, which goes against the principles of pure object-oriented programming.

    Java was developed by which of the following? - ProProfs

    Java was developed by which of the following?

    • Oracle

    • Sun

    • Microsoft

    • Google

    Correct Answer
    A. Sun
    Explanation
    Java was developed by Sun Microsystems. Sun Microsystems was a company that was founded in 1982 and played a significant role in the development of computer technologies. In the mid-1990s, a team of engineers at Sun Microsystems, led by James Gosling, developed the Java programming language. Java was designed to be a platform-independent language that could run on any device or operating system. Sun Microsystems later became a subsidiary of Oracle Corporation in 2010.

    Who created Java? - ProProfs

    Who created Java?

    • James Gosling

    • Patrick Naughton

    • Both a and b

    • None of the above

    Correct Answer
    A. Both a and b
    Explanation
    Both James Gosling and Patrick Naughton are credited as the creators of Java. They, along with a team of developers at Sun Microsystems, developed the programming language in the mid-1990s. James Gosling is often referred to as the "father of Java" as he played a key role in the design and implementation of the language, while Patrick Naughton made significant contributions to the development of the original Java compiler and runtime system. Therefore, the correct answer is that both James Gosling and Patrick Naughton created Java.
