As per the Java Code Conventions (http://www.oracle.com/technetwork/java/codeconventions-150003.pdf, Chapter 7.4):

if statements always use braces {}. Avoid the following error-prone form:

if (condition) //AVOID! THIS OMITS THE BRACES {}!
    statement;

From the old Java Code Conventions, it is the second.

Exact piece of the document: 7. Statements. 7.4 if, if-else, if-else-if-else Statements (page 12):

The if-else class of statements should have the following form

if (condition) {
    statements;
}

if (condition) {
    statements;
} else {
    statements;
}

if (condition) {
    statements;
} else if (condition) {
    statements;
} else if (condition) {
    statements;
}

Note: if statements always use braces {}. Avoid the following error-prone form:

if (condition) //AVOID! THIS OMITS THE BRACES {}!
    statement;

After that and since the Java Code Conventions are really old (since 1997), this falls into a personal matter/taste due to code readability. IMO the second is just fine.
