代码如下: publicclassMain{// ... 省略其他代码 ...publicstaticvoidcompareStrings(Stringstr1,Stringstr2){intlength1=str1.length();intlength2=str2.length();intminLength=Math.min(length1,length2);for(inti=0;i<minLength;i++){charchar1=str1.charAt(i);charchar2=str2.charAt(i);if(char1!
否则,它将返回false。 等于引用 在开始使用此方法之前,请确保String1不为空。 string1.equals(string2)是正确的方法。 String s ="something", t ="maybe something else"; if (s == t) // Legal, but usually results WRONG. if (s.equals(t)) // RIGHT way to check the two strings /* == w...
字符串操作类中s1.compareTo(s)规则: Compares two strings lexicographically. The comparison is based on the Unicode value of each character in the strings. The character sequence represented by thisStringobject is compared lexicographically to the character sequence represented by the argument string. T...
Compare strings to find out if they are equal, ignoring case differences: String myStr1 = "Hello"; String myStr2 = "HELLO"; String myStr3 = "Another String"; System.out.println(myStr1.equalsIgnoreCase(myStr2)); // true System.out.println(myStr1.equalsIgnoreCase(myStr3)); // false...
Example 2: Check if Two Strings are Equal classMain{publicstaticvoidmain(String[] args){ String str1 ="Learn Python"; String str2 ="Learn Java";// if str1 and str2 are equal, the result is 0 if(str1.compareTo(str2) ==0) { ...
StringmyStr1="Hello";StringmyStr2="Hello";System.out.println(myStr1.compareTo(myStr2));// Returns 0 because they are equal Try it Yourself » Definition and Usage ThecompareTo()method compares two strings lexicographically. The comparison is based on the Unicode value of each character in...
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);}} ...
compare(String str1, String str2) 比较两个字符串,返回一个int值 str1等于str2(或都为空)返回0 str1小于str2返回小于0 str1大于str2返回大于0 StringUtils.compare(null, null) = 0 StringUtils.compare(null , "a") < 0 StringUtils.compare("a", null) > 0 ...
(3)compareTo:比较两个String对象的值是否相等。例如: 1String str1 ="hello quanjizhu";2String str2 =str1+"haha";3String str3 =newString("hello quanjizhu");45System.out.println(str1.compareTo(str2));6System.out.println(str1.compareTo(str3)); ...
Java String compareTo() method example. Learn to compare two strings lexicographically. We can consider this string comparison dictionary based comparison.
