java - Comparing Boolean Value -


i have checkbox named testcheck. when user check value becomes true. able implement compare of true/false following ways

1.

if (testcheck.getvalue() == boolean.true) {     // respective code  }

2.

if (testcheck.getvalue().equals(boolean.true)) {     //respective code }

3.

if (testcheck.getvalue()) {     //respective code  }

my questions:

  • is there difference ?
  • if yes, 1 best way of implementation ?

it depends....

if return type of testcheck.getvalue() boolean, 3rd 1 ok.

but if boolean (big b), do:

boolean.true.equals(testcheck.getvalue())

to avoid npe during autoboxing.
