If two arraylists are not equal and we want to findwhat additional elements are in the first list compared to the second list, use theremoveAll()method. It removes all elements of the second list from the first list and leaves only additional elements in the first list. ArrayList<String>li...
This output demonstrates the effectiveness of theequalsmethod in comparing twoIntegerobjects. It provides a clear indication of whether the integers are equal or not, offering a simple and concise approach to integer comparison. Theequalsmethod is a valuable tool for comparingIntegerobjects in Java. ...
We can usecompareTo(Byte anotherByte)to compare two Byte objects numerically. The following table lists the return value fromcompareTo(Byte anotherByte). Let's give it a try. publicclassMain {publicstaticvoidmain(String[] args) {//fromjava2s.comByte byte1 =newByte("1"); Byte byte2 =ne...

Another approach is to use theequals()method in JavaDateclass. It compares two dates and returnstrueif they are equal. Example Codes: // java 1.8packagesimpletesting;importjava.text.ParseException;importjava.text.SimpleDateFormat;importjava.util.Date;publicclassSimpleTesting{publicstaticvoidmain(String...
The method Files::mismatch, added in Java 12, compares the contents of two files. It returns -1L if the files are identical, and otherwise, it returns the position in bytes of the first mismatch. This method internally reads chunks of data from the files’ InputStreams and uses Arrays::...
In this article, you'll learn how to compare two dates in Java using both Java 8 new date and time API and the legacy Date and Calendar API. Java 8 Date & Time API Java 8 introduced a brand new date and time API (classes in the java.time.* package) to fix the flaws in the ...
log('Objects are not equal.'); } // Objects are equal! This method works only when the key-value pairs have the same order. If the key-value pairs are arranged differently in the two objects but are the same, this method will return false: const obj1 = { burger: '🍔', pizza:...
This post will discuss how to compare two objects in Java. You should never use the==operator for comparing two objects, since the==operator performs a reference comparison and it simply checks if the two objects refer to the same instance or not. The recommended option to compare two object...
Strings1=newString("Compare two strings in Java"); Strings2=newString("Compare two strings in Java"); System.out.println(Objects.equals(s1,s2));// Evaluates to true System.out.println(Objects.equals(null,null));// Evaluates to true ...
