在Java中,可以使用compareTo方法来比较字符串。 public class CompareStrings { public static void main(String[] args) { String str1 = "Hello"; String str2 = "World"; int result = str1.compareTo(str2); if(result < 0) { System.out.println("str1 is less than str2"); } else if(resu...
There is also a third, less common way to compare Java strings, and that's with the String class compareTo method. If the two strings are exactly the same, the compareTo method will return a value of 0 (zero). Here's a quick example of what this String comparison approach looks like...
Java 8引入了lambda表达式,可以更加简洁地实现排序逻辑。 importjava.util.Arrays;publicclassStringSort{publicstaticvoidmain(String[]args){String[]strings={"apple","banana","grape"};Arrays.sort(strings,(str1,str2)->str1.length()-str2.length());for(Stringstr:strings){System.out.println(str);}}...
publicstaticvoidmain(String args[]){ Stringstr1="Strings"; Stringstr2="Strings"; Stringstr3="Strings123"; intresult=str1.compareTo( str2 ); System.out.println(result); result = str2.compareTo( str3 ); System.out.println(result); result = str3.compareTo( str1 ); System.out.println...
String secondString = "javablog"; String thirdString = "coderolls"; String fourthString = "CodeRolls"; System.out.println("Comparing strings using equals() and equalsIgnoreCase() method\n"); // Using equals() method System.out.print("firstString.equals(secondString) : "); ...
publicclassTest{publicstaticvoidmain(Stringargs[]){Stringstr1="Strings";Stringstr2="Strings";Stringstr3="Strings123";intresult=str1.compareTo(str2);System.out.println(result);result=str2.compareTo(str3);System.out.println(result);result=str3.compareTo(str1);System.out.println(result);}} ...
JAVA 关于String的CompareTo方法即字典序比较 按字典顺序比较两个字符串。该比较基于字符串中各个字符的 Unicode 值。将此String对象表示的字符序列与参数字符串所表示的字符序列进行比较。如果按字典顺序此String对象在参数字符串之前,则比较结果为一个负整数。如果按字典顺序此String对象位于参数字符串之后,则比较结果为...
//Different strings assertThat(name.compareTo("alexa"), lessThan(0)); assertThat(name.compareTo("ale"), greaterThan(0)); 4.compareTo()和equals()的区别 CompareTo() 和equals()方法之间的区别是: Compare()按字典顺序进行比较(字典排序),而equals()检查两个字符串的内容,尽管这两种方法都区分大小写...
String str1 = "Strings"; String str2 = "Strings"; String str3 = "Strings123"; int result = str1.compareTo( str2 ); System.out.println(result); result = str2.compareTo( str3 ); System.out.println(result); result = str3.compareTo( str1 ); ...
You can use a map to code the Strings and their values. The benefit of this approach is that it has O(1) complexity as oppose to use of an array for instance. Map<String, Integer> map = Map.of("one", 1, "two", 2, ...); public int compare(String a, String b) { return ...
