Java learnings

• There are two levels in java. Language level and binary level. We can code in Java 8 by setting the language level to java 8 but we can compile the code to java 7.
• Mostly all parts are extensions of the java previous versions and can be compiled to equivalent previous java binary construct.
• This is useful if certain library dosent work with the java 8 binary. for eg tha asm in spring 3 dosent work with java 8. If we want asm to work we need to upgrade to spring 4. But upgrading to spring 4 is not possible. So we can compile the code to java 7 by setting binary level to 7.
• But what if we have java 8 constructs. the java compiler will try to compile them to equivalent java 7 binary construct. If it cant the compilation will fail and we will have to revert to upgrading spring.

Java 8
