Different types of languages exist in object-oriented programming such as JAVA, Visual Basic etc. . It comprises a set of instructions that are used to produce various kinds of output. 4GLs make programming easier, more efficient, and more effective for users with less programming skills. Machine level language or First-generation language (the mid 1940s), Assembly level language or Second-generation language (1950s to 1958s), High-level language or Third-generation language (1958s to 1985s), Fourth-generation language (1985s to till now). Even with its limitations, this approach supported highly sophisticated applications. It is a non-procedural language which means that the programmer defines what has to be done instead of how the task is to be completed.I4GL is more familiar and similar to human language.
