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 cha
String anotherString = (String)anObject; int n = value.length; if (n == anotherString.value.length) { char v1 = value; char v2 = anotherString.value; int i = 0; while (n-- != 0) { if (v1) return false; i++; } return true; } } return false; } 这就是String重写的equa...
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...

String anotherString = (String)anObject;int n = value.length;// 3. this和anObject两个字符串的长度是否相同，是继续比较，否则返回false if (n == anotherString.value.length) { char v1[] = value;char v2[] = anotherString.value;int i = 0;// 4. 按照字典序，从前往后逐个字符进行比较 whi...
