CallToSuspiciousStringMethod

Reports calls of:

• equals()
• equalsIgnoreCase()
• compareTo()
• compareToIgnoreCase() and
• trim()

on String objects. Comparison of internationalized strings should probably use a java.text.Collator instead. String.trim() only removes control characters between 0x00 and 0x20. The String.strip() method introduced in Java 11 is more Unicode aware and can be used as a replacement.
