Java is a static language, mainly used for back-end development, while JavaScript is a dynamic language, mainly used for front-end development. Although Java and JavaScript are both programming languages, they are no more similar than two other randomly picked programming languages.

Java and JavaScript are related because JavaScript has always been a Web programming language, while Java started in the Web and gained a high reputation there. Therefore, some people mistakenly believe that proficiency in Java requires proficiency in JavaScript, and this statement is obviously a misunderstanding.
