Q1. What does a Java Developer do?

A small team called ‘The Green Team’ initially conceptualized Java in the early 1990s. That team included James Gosling, who later became known as the ‘Father of Java’ for his work. Gosling developed Java while working as an engineer at Sun Microsystems (a subsidiary of Oracle today). In general, senior web developers earn the most working in the media industry, with an average salary of $116,206.

Prior to the introduction of generics, each variable declaration had to be of a specific type. For container classes, for example, this is a problem because there is no easy way to create a container that accepts only specific types of objects. Either the container operates on all subtypes of a class or interface, usually Object, or a different container class has to be created for each contained class. Generics allow compile-time type checking without having to create many container classes, each containing almost identical code. In addition to enabling more efficient code, certain runtime exceptions are prevented from occurring, by issuing compile-time errors. If Java prevented all runtime type errors (ClassCastExceptions) from occurring, it would be type safe.
