Best way would be to declare Boolean variable within the code block and return it at end of code  like this   public boolean Test        boolean booleanFlag  true       if  A gt B       booleanFlag  true       else       booleanFlag   false       return booleanFlag       I find this the best way

You re allowed to have more than one return statement  so it s legal to write  if  some condition      return true    return false    It s also unnecessary to compare boolean values to true or false  so you can write  if  verifyPwd            do task       Edit  Sometimes you can t return early because there s more work to be done   In that case you can declare a boolean variable and set it appropriately inside the conditional blocks   boolean success   true   if  some condition         Handle the condition    success   false    else if  some other condition         Handle the other condition    success   false    if  another condition         Handle the third condition        Do some more critical things   return success

You can also do this  for readability s sake  boolean passwordVerified  pword equals pwdRetypePwd getText      if  passwordVerified        txtaError setEditable true       txtaError setText   Password didn t match         txtaError setForeground Color red       txtaError setEditable false    else      addNewUser      return passwordVerified
