boolean b[] = new boolean [100];

<http://docs.oracle.com/javase/specs/jls/se7/html/jls-15.html#jls-15.10.1>

If you want to initialize array elements to a value that is not the default you 
have to loop.

Or use the 'java.util.Arrays' class.
<http://docs.oracle.com/javase/7/docs/api/java/util/Arrays.html#fill(boolean[],
boolean)>

Every Java programmer should know the collections framework and key utility 
classes like 'Arrays'.
