EBWB - Enclosing Body Within a Block

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

Wrong

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

Tip: Always enclose body within a block

Right

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