public static int compareCustom(String s1, String s2) { for (int i = 0; i < s1.length() && i< s2.length(); i++) { if(s1.charAt(i) == s2.charAt(i)){ //System.out.println("Equal"); continue; } else{ return s1.charAt(i) - s2.charAt(i); } } if(s1.length()<s2....
We can compare String in Java on the basis of content and reference.It is used in authentication (by equals() method), sorting (by compareTo() method), reference matching (by == operator) etc.There are three ways to compare String in Java:...
String s5 = "cdfg"; System.out.println( s1.compareTo(s2) ); // -1 (前面相等,s1长度小1) System.out.println( s1.compareTo(s3) ); // -3 (前面相等,s1长度小3) System.out.println( s1.compareTo(s4) ); // 48 ("a"的ASCII码是97,"1"的的ASCII码是49,所以返回48) System.out....
在Java中,String类型是不可变的,所以当我们需要对String类型进行比较排序时,我们需要借助一些内置方法或者自定义比较器来实现。下面将介绍几种常见的String比较排序方法。 方法一:使用compareTo方法 Java中的String类提供了compareTo方法,可以用来比较两个字符串的大小。该方法返回一个int值,如果字符串相等返回0,如果字符...

Java的String类包含了很多对字符串执行各种操作的方法,例如compare()、concat()、equals()、split ()、length()、replace()、compareTo()、substring() 等。在这些方法中,我们将重点关注 compareTo() 方法。 String.compareTo() 方法 Java String 类 compareTo() 方法按字典顺序将给定字符串与当前字符串进行比较...
楼主请看一下java api中对String类中compareTo方法的解释，1.result.compareTo(result2)) 是根据第一个红框标注的方法比较的，即返回这两个字符串在位置 k 处两个char 值的差 2."hello".compareTo("hello,")则是根据第二个红框标注的方式进行比较的，即返回这两个字符串长度的差 请楼主采纳 ...

CompareToIgnoreCase(String) Compares two strings lexicographically, ignoring case differences. Concat(String) Concatenates the specified string to the end of...
