接下来,我们需要将提取的数字转换为整数,以便进行比较。可以使用Java的Integer类来实现这一步骤。以下是具体的代码: importjava.util.Scanner;publicclassCompareNumbers{publicstaticvoidmain(String[]args){Scannerscanner=newScanner(System.in);System.out.println("请输入第一个字符串:");Stringstr1=scanner.nextLine...
public static void main(String[] args) { String sys = "学生信息管理"; System.out.println("欢迎进入《" + sys + "》系统"); System.out.println("请设置一个管理员密码:"); Scanner input = new Scanner(System.in); String pass = input.next(); // 设置密码 System.out.println("重复管理员...
Java中的compareto方法,返回参与比较的前后两个字符串的asc码的差值 String a = “a”; String b = “b”; System.out.println(a.compareTo(b)); 输出值-1 1 2 3 4 5 String a = “b”; String b = “a”; System.out.println(a.compareTo(b)); 输出值1 1 2 3 4 5 String a = “a...
一.首先先来看下java.lang.String这个类下面的equals方法是如何实现的。 public booleanequals(Object anObject) { if (this ==anObject) { //判断对象的地址是否一致 return true; } if (anObject instanceofString) { //判断anObject是否是String类型 ...
CompareTo()方法是java.lang.Comparable接口的一个抽象方法。 其方法的主要作用是根据依据比较 对象的大小,比如Integer型,比较的是数值的大小,String形等, 调用这个方法的对象比 形参对象大的话返回 1 比形参小的话 返回 -1 等于 形参的话 返回 0 根据返回的值就可以确定两个对象的大小 进而进行排列。 注:当在...

String类compareTo比较日期 String类compareTo⽐较⽇期 int java.lang.String.compareTo(String anotherString) Compares two strings lexicographically（字典序; 按字典顺序;）.The comparison is based on the Unicode value of each character in the strings.The character sequence represented by this String ...
In this case, compareTo returns the difference of the lengths of the strings -- that is, the value: <blockquote> text/java Копировать this.length()-anotherString.length() </blockquote> For finer-grained String comparison, refer to java.text.Collator. Java documentation for...
