What does this operatoer

 

This question already has an answer here:

  • Shortcut “or-assignment” (|=) operator in Java 8 answers
  • What does “|=” mean? (pipe equal operator) 6 answers 
    • noti.flags |= Notification.FLAG_AUTO_CANCEL;

    means 

    noti.flags = noti.flags | Notification.FLAG_AUTO_CANCEL;

    where | is the Bit wise OR operator

  • | is the bit a bit or operator

  • |= is noti.flags = noti.flags | Notification.FLAG_AUTO_CANCEL;

    noti.flags |= Notification.FLAG_AUTO_CANCEL;

    calculates the bitwise OR of the noti.flags and Notification.FLAG_AUTO_CANCEL, and assigns the result to noti.flagsd.

    • bitwise or, is the same as: 

    noti.flags = noti.flags | Notification.FLAG_AUTO_CANCEL;

    it executes an "or" operation with the bits of the operands. Say that you have 

    // noti.flags =                      0001011    (11 decimal)
// Notification.FLAG_AUTO_CANCEL =   1000001    (65 decimal)

// The result would be:              1001011    (75 decimal)
