The result is a positive integer if this String object lexicographically follows the argument string. The result is zero if the strings are equal; compareTo returns 0 exactly when the #equals(Object) method would return true. This is the definition of lexicographic ordering. If two strings are...
StringmyStr1="Hello";StringmyStr2="Hello";System.out.println(myStr1.compareTo(myStr2));// Returns 0 because they are equal Try it Yourself » Definition and Usage ThecompareTo()method compares two strings lexicographically. The comparison is based on the Unicode value of each character in...

System.out.println(String.valueOf(num1).compareTo(String.valueOf(num2)));//-1 6.compareToIgnoreCase忽略大小写 不考虑大小写,按字典顺序比较两个字符串。此方法返回一个整数,它的正负号是调用 compareTo 的正负号,调用时使用了字符串的规范化版本,其大小写差异已通过对每个字符调用 Character.toLowerCase(...
