# Introduction
Prettier Java is an opinionated Java code formatter.
It removes all original styling and ensures that all outputted code conforms to a consistent style.
Prettier Java takes your code and reprints it from scratch by taking the line length into account.
For example, take the following code:
```java
foo(arg1, arg2, arg3, arg4);
```
It fits in a single line so it's going to stay as is. However, we've all run into this situation:
<!-- prettier-ignore -->
```java
foo(reallyLongArg(), omgSoManyParameters(), IShouldRefactorThis(), isThereSeriouslyAnotherOne());
```
Suddenly our previous format for calling function breaks down because this is too long. Prettier Java is going to do the painstaking work of reprinting it like that for you:
```java
foo(
reallyLongArg(),
omgSoManyParameters(),
IShouldRefactorThis(),
isThereSeriouslyAnotherOne()
);
```
Prettier Java enforces a consistent code **style** (i.e. code formatting that won't affect the AST) across your entire codebase because it disregards the original styling by parsing it away and re-printing the parsed AST with its own rules that take the maximum line length into account, wrapping code when necessary.
