c. Java does not have object-oriented programming features, although Java syntax is derived from C++.

d. Java Development Kit (JDK) is the software required to run any application deployed on the Java platform.

Explanation / Answer

ANS-

1- Java was designed by IBM for developing applications on mobile devices in the early 1980s.-FALSE

because the first public implementation of java was released in 1995 by sun microsystems as java 1.0.

2-Java Virtual Machine makes programs written in Java platform independently, i.e., the programs can run on different types of hardware.-TRUE

because jvm is platform dependent and java is platform dependent which means java virtual machines is different for different machines but java code once written on any machine or hardware can be executed by any machine using jvm compatible for that machine.

3-Java does not have object-oriented programming features, although Java syntax is derived from C++.-FALSE java supports for various object oriented fatures such as classes , objects, inheritance,polymorphism etc all these features are used in java .

4-Java Development Kit (JDK) is the software required to run any application deployed on the Java platform.-TRUE because java development kit is the software required to run any application deployed on the Java platform.it is basically combination of the jvm + the interpreter.
