In this tutorial I will show you how to make Eclipse auto complete what you are writing.
Sometimes pieces of code, such as variables, have a pretty long name for clarity. For example a parameter in a method could be par1IconRegister. You don’t really want to write that name every time, because it’s pretty long. Once you are at par1 there aren’t any other variables that have the same name. At this point try pressing Ctrl, Space which will auto fill the rest of the parameter name without you having to write it. This works on many things such as method names, variable names and parameter names.
