In this tutorial, we shall see how to check if two Strings are equal in Java using the method String.equals(String anotherString). Also, we shall go through an example Java program to ignore the case of the characters in the string, and check if two Strings are equal. Examples 1. Che...
the value 0 if the argument string is equal to this string; a value less than 0 if this string is lexicographically less than the string argument; and a value greater than 0 if this string is lexicographically greater than the string argument. 在爱词霸上的翻译如下: 如果参数字符串等于此字符...
