What will be the output of the following program?
public class Replace {
public static void main(String a[]) {
String replaceStr = "<B>Good Day<\\B>";
System.out.println("Before replace: " + replaceStr);
replaceStr = replaceStr.replaceAll("[a-zA-Z<> \\]", "");
System.out.println("After replace: " + replaceStr);
}
}
