Enclosing Body Within a Block (EBWB)

Description:

The statement of a loop should always be a block. The then and else parts of if-statements should always be blocks. This makes it easier to add statements without accidentally introducing bugs due to forgetting to add braces.

Example:

if( st == null ) 
    return;
while( st.countTokens() > 2 )
    s += st.nextToken();
