JarCheck is a Java class checking program which looks at all classes to be loaded or access by a Java program and verifies that they are compatible with that version of Java. Java programs can be called in order to load them into Java and the targeted Java version can be added to the call in order to ensure that the program is able to run with that version of Java. Alternative, two version numbers can be added in order to create a spread of compatible Java version numbers from one number to another, i.e. 1.1 1.8 will load the Java program it is is running versions of programs that will execute using Java 1.1 through to Java 1.8.

JarCheck Key Features:

• Java program that can check whether a Java class is compatible with a certain version of Java before loading it and creating an error message
• Check that a Java class works with one Java version number
• Check that a Java class will work with one of several Java versions i.e. from 1.1 to 1.8
• Requires Java 1.7 or later
• Requires Windows

JarCheck is a Java class version checker to ensure full compatibility with the installed Java version.
