4.3.2. White Space

Controls the white space handling for the individual components of Java statements.

4.3.2.1. Space before

Lets you choose the components that should get one leading space inserted before them.

Method declaration parentheses

Example 4.9. Method declaration parentheses

public void someMethod()) {
  ...
}

public void someMethod ()) {
  ...
}

Method call parentheses

Example 4.10. Method call parentheses

for (Iterator i = pointList.iterator(); i.hasNext();) {
    ...
}

for (Iterator i = pointList.iterator (); i.hasNext ();) {
    ...
}

Statement parentheses

Example 4.11. Statement parentheses

while(!isDone)
    doSomething();

while (!isDone)
    doSomething();

Braces

Example 4.12. Braces

    String[] values = new String[]{
        "One", "Two", "Three", "Four", "Five", "Six", "Seven"
    };

    String[] values = new String[] {
        "One", "Two", "Three", "Four", "Five", "Six", "Seven"
    };

Brackets

Example 4.13. Brackets

for (i = 0; i < 100; i++)
    sum += value[i];

for (i = 0; i < 100; i++)
    sum += value [i];

Brackets in types

Example 4.14. Brackets in types

String[] names = (String[])data.toArray(new String[]);

String [] names = (String [])data.toArray(new String []);

Case colon

Example 4.15. Case colon

switch (character) {
    case 'A':
        break;
}

switch (character) {
    case 'A' :
        break;
}

4.3.2.2. Space after

Lets you choose what components should have one trailing space inserted after the component.

Comma

Example 4.16. Comma

doSomething (a,b,c,d);

doSomething (a, b, c, d);

Semicolon

Example 4.17. Semicolon

for (i=0;i<10;i++) ...

for (i=0; i<10; i++) ...

Type Cast

Example 4.18. Type Cast

int line = ((JavaAST)node).getStartLine();

int line = ((JavaAST) node).getStartLine();

Negation
Prints a space after the unary operators Logical NOT (!) and Bitwise NOT (~).
Example 4.19. Logical NOT
while(!isDone) { doSomething(); } while(! isDone) { doSomething(); }

4.3.2.3. Spaces around

Controls what components should have both a leading and trailing space inserted. This is sometimes called "padding".

Assignment Operators
Example 4.20. Assignment Operators (=, +=, -=, *=, \=, %=, &=, |=, ^=, <<=, >>=, >>>=)
a=(b+c)*d; a = (b+c)*d;

Logical Operators

Example 4.21. Logical Operators (&&, ||)

if((LA(1)=='/')&&(LA(2)!='*'||(LA(2)=='*'&&LA(3)!='*'))) ...

if((LA(1)=='/') && (LA(2)!='*' || (LA(2)=='*' && LA(3)!='*'))) ...

Relational Operators

Example 4.22. Relational Operators (==, !=, <, >, <=, >=)

if((LA(1)=='\n'||LA(1)=='\r')) ...

if((LA(1) == '\n'||LA(1) == '\r')) ...

Bitwise Operators

Example 4.23. Bitwise Operators (&, |, ^)

public static final boolean isUnix()
{
    return (getOperatingSystem()&PLAT_UNIX) != 0;
}

public static final boolean isUnix()
{
    return (getOperatingSystem() & PLAT_UNIX) != 0;
}

Mathematical Operators
Example 4.24. Mathematical Operators (+, -, /, *, %)
a=(b+c)*d; a=(b + c) * d;

Shift Operators

Example 4.25. Shift Operators (<<, >>, >>>)

if(((1L<<i)&l)!=0)
    System.out.print("1");

if(((1L << i)&l)!=0)
    System.out.print("1");

Braces

Example 4.26. Braces

Object[] items = {"2", "3", "4"};

Object[] items = { "2", "3", "4" };

Brackets

Example 4.27. Brackets

for (i = 0; i < 100; i++)
    sum += value[i];

for(i = 0; i < 100; i++)
    sum += value[ i ];

Parentheses

Example 4.28. Parentheses

GridBagLayout layout = new GridBagLayout();
setLayout(layout);

GridBagLayout layout = new GridBagLayout();
setLayout( layout );

Type Cast Parentheses

Example 4.29. Type Cast Parentheses

int line = ((JavaAST)node).getStartLine();

int line = (( JavaAST )node).getStartLine();
