Here are five interesting facts about Java:

1. Originally Called Oak
   Java was initially named Oak after an oak tree that stood outside the office of James Gosling, one of the creators of Java, at Sun Microsystems. It was later renamed Java, inspired by Java coffee, reflecting the creators' love for coffee.

2. Platform Independence
   One of Java’s key strengths is its platform independence. The Java mantra, "write once, run anywhere" (WORA), means that code written in Java can run on any device equipped with a Java Virtual Machine (JVM). This is achieved through the use of bytecode, which is an intermediate representation of the compiled Java code that the JVM can execute on any platform.
