How do I compare strings in Java? 1. 语法知识 ==:判断的是引用的相等性(reference equality),也即是否为同一对象; .equals():判断的是值的相等性(value equality),也即是否在逻辑上相等; 2. 举例 new String(“test”).equals(“test”) // –> true // These two have the same value new Strin...
Furthermore, this method can be used to sort a list ofStringswithnullentries: assertThat(StringUtils.compare(null, null)) .isEqualTo(0); assertThat(StringUtils.compare(null, "abc")) .isEqualTo(-1); assertThat(StringUtils.compare("abc", "bbc")) .isEqualTo(-1); assertThat(StringUtils.compa...

(1)不忽略字符串大小写情况下字符串的大小比较方法compareTo(another str) 格式:int result = str1.compareTo(str2); 输出三种比较结果:若该字符串的Unicode值<参数字符串的Unicode值,结果返回一负整数;若若该字符串的Unicode值=参数字符串的Unicode值,结果返回0;若该字符串的Unicode值>参数字符串的Unicode值,结...
int compareToIgnoreCase(String str)Compares two strings lexicographically, ignoring differences in case. Returns an integer indicating whether this string is greater than (result is > 0), equal to (result is = 0), or less than (result is < 0) the argument. ...
