• ternary operators java 6 answers

can please explain, in simple english, logic behind statement?

return mcontainsloadingrow ? (getcontentdatasize() + 1) : getcontentdatasize(); 

assuming mcontainsloadingrow boolean, if mcontainsloadingrow true,

then return getcontentdatasize() + 1.

if not, return getcontentdatasize().

is correct way @ this?

this complete expression know as ternary operator in java.

code statement

mcontainsloadingrow ? (getcontentdatasize() + 1) : getcontentdatasize();         ||                       ||                         ||  //boolean expression      //return if true          //return if false 

here in code

mcontainsloadingrow boolean variable contains either true or false. can change mcontainsloadingrow boolean expression (a>b or b==a or b <= etc.)

? (question mark) :- enables fine whether true or false.

if true expression (getcontentdatasize() + 1) return.

if false expressin getcontentdatasize() value return.
