Java is a programming language originally developed by James Gosling at Sun Microsystems. Java is an object-oriented language similar to C++. The language was initially called Oak after an oak tree that stood outside Gosling’s office, but a different organization named OAK TECHNOLOGIES was already trademarked the name. So they decided to rename the name to Java, a type of coffee which the developers were drinking while thinking of a new name. Hence you see a cup of hot tea as their logo in java applications.
