5.如果参数是String类型,字符数组的长度一致,但是从左到右如果遇到字符不一致则返回false 二.java.lang.String这个类下面的compareTo方法是如何实现的。 AI检测代码解析 public int compareTo(String anotherString) { int len1 = value.length; int len2 = anotherString.value.length; int lim = Math.min(len...
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 ...
String类compareTo比较日期 int java.lang.String.compareTo(String anotherString)Compares two stringslexicographically(字典序; 按字典顺序;). The comparison is based on theUnicodevalue of each character in the strings. The character sequence represented by this String object is compared lexicographically to...
text/java this.charAt(k)-anotherString.charAt(k) </blockquote> 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: <block...
