What is the difference between the JDK6 java.util.regex.Pattern's "Boundary matchers" '\z' and '\Z'?
Background: I was trying to read a UTF-8 encoded file's contents into a String.
Can anybody elaborate the difference between “Char” and “String” at Java

The difference is anchor \Z matches the empty string just before the newline, while \z matches empty string after the newline.
A very simple example to understand this is:
System.out.println("abc\n".matches("abc\\Z\\n")); // trueSystem.out.println("abc\n".matches("abc\\z\\n")); // false
System.out.println("abc\n".matches("abc\\n\\z")); // true
