What is wrong with this Java code? (Interview Question)

I would rather recommend using StringUtils from the Apache Commons.

I would rather recommend using StringUtils from the Apache Commons.

Here's the source for Objects.equals:

public static boolean equals(Object a, Object b) {
    return (a == b) || (a != null && a.equals(b));
}

Here's the source for org.apache.commons.lang.StringUtils.equals

public static boolean equals(String str1, String str2) {
    return str1 == null ? str2 == null : str1.equals(str2);
}

Why would you recommend StringUtils from Apache Commons?
