## Braces Rules

The Braces Ruleset contains a collection of braces rules.

### IfStmtsMustUseBraces

Avoid using if statements without using curly braces

This rule is defined by the following XPath expression:

    //IfStatement[count(*) &lt; 3][not(Statement/Block)]

Here's an example of code that would trigger this rule:

     public class Foo {
       public void bar() {
         int x = 0;
         if (foo) x++;
       }
     }

### WhileLoopsMustUseBraces

Avoid using 'while' statements without using curly braces

This rule is defined by the following XPath expression:

    //WhileStatement[not(Statement/Block)]

Here's an example of code that would trigger this rule:

    public void doSomething() {
      while (true)
          x++;
    }

### IfElseStmtsMustUseBraces

Avoid using if..else statements without using curly braces

This rule is defined by the following XPath expression:

    //Statement
     [parent::IfStatement[@Else='true']]
     [not(child::Block)]
     [not(child::IfStatement)]

Here's an example of code that would trigger this rule:

     public void doSomething() {
       // this is OK
       if (foo) x++;
       // but this is not
       if (foo)
           x=x+1;
       else
           x=x-1;
     }

### ForLoopsMustUseBraces

Avoid using 'for' statements without using curly braces

This rule is defined by the following XPath expression:

    //ForStatement[not(Statement/Block)]

Here's an example of code that would trigger this rule:

    public void foo() {
     for (int i=0; i&lt;42;i++)
       foo();
    }
