二.java.lang.String这个类下面的compareTo方法是如何实现的。 publicintcompareTo(String anotherString) {intlen1 =value.length;intlen2 =anotherString.value.length;intlim =Math.min(len1, len2);charv1[] =value;charv2[] =anotherString.value;intk = 0;while(k <lim) {charc1 =v1[k];charc2...
String str1 = "sachin tendulkar";String str2 = "amrood admin";String str3 = "amrood admin";// checking for equality boolean retval1 = str2.equals(str1);boolean retval2 = str2.equals(str3);// prints the return value System.out.println("str2 is equal to str1 = " + ...
还值得注意的是,参数顺序实际上是(Object expected, Object actual),因此outContent应该排在第二位,因为这是“实际”输出。 您可以使用 AssertJ“isEqualToNormalizingNewline”,如下所示: importstatic org.assertj.core.api.Assertions.assertThat;...@Testpublicvoid ingoreLineEndingCharacterTest() { assertThat("F...
使用equalsIgnoreCase方法比较String是否相等(不区分大小写) 如果我们想要比较两个String对象是否相等,但是不区分大小写,可以使用equalsIgnoreCase方法。该方法会忽略大小写比较两个String对象的内容。 Stringstr1="Hello";Stringstr2="hello";booleanisEqual=str1.equalsIgnoreCase(str2);// trueSystem.out.println(isEqual)...
A pool of strings, initially empty, is maintained privately by the class String. When the intern method is invoked, if the pool already contains a string equal to this String object as determined by the equals(Object) method, then the string from the pool is returned. Otherwise, this String...

Java中的字符串类String提供了一个名为equals的方法,用于判断两个字符串是否相等。这个方法会比较字符串的内容,而不是比较字符串的引用。 Stringstr1="Hello";Stringstr2="World";Stringstr3="Hello";booleanisEqual1=str1.equals(str2);booleanisEqual2=str1.equals(str3);System.out.println(isEqual1);//...
