## Code style: Remove unnecessary statements and keywords

17.01.2008 · [Christian Ullenboom](https://www.tutego.de/blog/javainsel/author/admin/)

Bad

Good

```java
**import java.lang.*;**

import java.util.*;

import java.util.Scanner;

**import java.util.*;**

class MyClass extends Object { }

class MyClass { }

class MyClass {

 int i = 0;

 boolean b = false;

 char c = '\\u0000';

 String s = null;

 double d = 0.0;

}

class MyClass {

 int i;

 boolean b;

 char c;

 String s;

 double d;

}

class MyClass {

 MyClass() { super(); }

}

class MyClass {

 MyClass() { }

}

interface MyInterface {

 public abstract void foo();

}

interface MyInterface {

 void foo();

}

void lollipop() {

 return;

}

void lollipop() {

}

java.lang.String s;

String s;

Object[] param = new Object[ 1 ];

param[ 0 ] = i;

Object[] param = { i };
```

Something missing?
