Java 语言(一种计算机语言,尤用于创建网站)// Java program to demonstrate // use of .compareTo operator in Java class GFG { public static void main(String[] args) { // Get some Strings to compare String s1 = "A"; String s2 = "A"; String s3 = "a"; String s4 = new String("A"...
If there is no index position at which they differ, then the shorter string lexicographically precedes the longer string. In this case,compareToreturns the difference of the lengths of the strings -- that is, the value: this.length()-anotherString.length() 1.当字符串s1和s都表示数字时,有三...
问比较compareTo()中的两个泛型EN您不需要编写compareTo方法。测试类应该实现类似的接口。
还建议我实现IEquatable<T>和非泛型IComparable。如果我这样做,我必须或被鼓励:实现CompareTo(Object)实现Operator ==(T, T)实现Opera 浏览0提问于2018-12-19得票数 6 回答已采纳 1回答 使用IEquatable<T>测试对象集合的相等性 、、、 我有一个实现IEquatable<T>的类,这样当我进行测试时,我可以使用如下调用...
then the string whose character at position k has the smaller value, as determined by using the < operator,lexicographically precedes the other string. In this case, compareTo returns the difference of the two character values at position k in the two string -- that is, the value: ...

Learn about the differences between equals, matches, and compareTo methods in Java String comparison. Understand how to effectively compare strings in your Java applications.
Comparing objects is somewhat awkward, so a === operator has been proposed. One proposal is that a === bwould be the same as((a == b) || ((a != null) && a.equals(b))) Common Errors Using == instead ofequals()with Objects ...
If they have different characters at one or more index positions, let k be the smallest such index; then the string whose character at position k has the smaller value, as determined by using the < operator, lexicographically precedes the other string. In this case, compareTo returns the ...
