Description

Strings should be compared with the equals() method, not == or !=.

This program uses == or != to compare two strings for equality, which compares two objects for equality, not their values. Chances are good that the two references will never be equal.

Risk Factors

TBD

Examples

The following branch will never be taken.

	  if (args[0] == STRING_CONSTANT) {
		  logger.info("miracle");
	  }
