很容易搜索到 COMPACT_STRINGS 的定义和说明: /** * If String compaction is disabled, the bytes in {@code value} are * always encoded in UTF16. * * For methods with several possible implementation paths, when String * compaction is disabled, only one code path is taken. * * The instance...
由上边我们可以看出,String类中的equals方法是对父类Object类中的equals方法的覆盖,先来看下Object类的equals方法怎么写的: *@param obj the reference object with which to compare. *@return {@codetrue}ifthis object is the same as the obj * argument; {@codefalse} otherwise. *@see #hashCode() *@...
Theequals()method returnstrueif twostringsare identical andfalseif the strings are different. Example classMain{publicstaticvoidmain(String[] args){ String str1 ="Learn Java"; String str2 ="Learn Java";// comparing str1 with str2 booleanresult = str1.equals(str2); System.out.println(resul...

ExampleGet your own Java Server Compare strings to find out if they are equal: StringmyStr1="Hello";StringmyStr2="Hello";StringmyStr3="Another String";System.out.println(myStr1.equals(myStr2));// Returns true because they are equalSystem.out.println(myStr1.equals(myStr3));// false...
Comparing two Strings with same content using equals method:true Comparing two reference pointing to same String with == operator:true ==与equals在对象之间的对比 另一中情景是:当你对比两个对象时,在选择==和equals方法中很容易困惑,当你比较的两个引用指向的对象是Object的类型的时候,那么你看到的结果和...
Java中"String.equals()“和"=="的区别 DoNOTuse the `==`` operator to test whether two strings are equal! It only determines whether or not the strings are stored in the same location. Sure, if strings are in the same location, they must be equal. But it is entirely possible to ...
Never use'=='operator for checking the strings equality. It verifies the object references, not the content, which is undesirable in most cases. 1. String.equals() API TheString.equals()in Java compares a string with the object passed as the method argument. It returnstrueif and only if:...
