if(str){ , or if(!str){ can it work in java ?

Hello all

im kinda new to java I wander

in some scripting lang sometimes you can query if the variables is set or contains value that is different from "" (empty string 0 length)

by simply

doing

if(str){厖.}

or

if(!str){ ?.}

in java I notice you can't do it if your variable is not Boolean , or do I miss here something and there is way to do that somehow

can someone please make it more clear to me , tnx
