If any particular method encountered the concurrent in a multi threaded Java environment during the resource detection then the ConcurrentModificationException might be thrown. In this process the object is a non permissible unit here. Here is an example related to the ConcurrentModificationException in Java − Exception in thread "main" java.util.ConcurrentModificationException at java.base/java.util.ArrayList$Itr.checkForComodification(ArrayList.java:000) at java.base/java.util.ArrayList$Itr.next(ArrayList.java:000) atcom.journaldev.ConcurrentModificationException.ConcurrentModificationExceptio nExample.main(ConcurrentModificationExceptionExample.java:00) For this particular process the exception is achieveable when − The exception detected and iteration is in not defined in the method. When the process blocked in a loop of fail fast iterator by using an internal flag called modCount. ... Read More

What is Concrete Class in Java? The concrete class is a base regular implementation which is declared initially for the all other methods related to it. This class do not have any unimplemented method, which is also can be extended to an abstract class on an interface class. We can create an object class by using a new key word class. The process can inherit an another abstract class. This process is also known as the 100% implemented class present in Java. Advantages and Disadvantages of a Concrete Class in Java There are so many advantages and disadvantages of a ... Read More

Reading data of a particular file and and compress some files into a zip, is a process of encapsulation in Java. There are two compressing and decompressing classes in a Java environment, which provides the data deflate compression format. They are − DeflaterOutputStream class − used to compress the files into a deflate format such as GZIPOutputStream. InflaterInputStream class − used to decompress the files in a deflate format such as GZIPInputStream. Example Here is an example of the process how we can compress a file into a Zip file in Java − try { File file ... Read More

What is Compiler Class In Java? A native code is a coding formation that can be run in a Java Virtual Machine. The compiler class, provides a support as well as give us a space to convert a Java code to a native code. This a public package which embedded in java.lang.Compiler.command() package in a Java environment. Example of a Compiler Class in Java Here is an example for a compiler class in Java − class of the NewClass$CompilerClass Name Value Is: null value Is the compilation successful here? : false value Is the compilation successful using str ...

The polymorphism is a declaration of an object capacity present in a Java environment. It allows us to perform the same process in different manner. There are two types of polymorphism present in Java − Compile-time polymorphism method Run time polymorphism method Today, we are going to discuss about the compile time polymorphism by using the Method overloading and Operator overloading. Compile Time Polymorphism Example Here is an example − void ARBRDD() { ... } void ARBRDD(int num1 ) { ... } void ARBRDD(float num1) { ... } void ARBRDD(int num1 , float num2 ) { ... ... Read More

How to Compare Two ArrayList In Java? There are various methods available, to compare the two particular array lists by using a Java environment. It consists of the array lists, as they are same in the size and should contain with the same elements in that particular lists. Difference Methods to Compare Two ArrayList In Java Here are some process mentioned below − Java equals() method Java removeAll() method Java retainAll() method Java ArrayList.contains() method Java contentEquals() method java.util.ArrayList method For this process − This particular function has a single parameter value to be compared for the ...

Stream is a pipeline system, which is mainly used to aggregate some operations like (filter(), map(), forEach(), and collect()) in a Java environment. This function consists of a source which is followed by the value of zero and then terminate the operation. A function is an input output stream whis mainly depends on the input arguments. Every stream works when − It starts from a data source. Process the data elements through a pipeline. Terminates itself in a terminal operation. Example of Comparing Streams to Loops Here is an example − Benchmark Is Here Mode Cnt Score ... Read More

There are three types of most important classes we can find in a Java environment, related to date and time. LocalDate, LocalTime and LocalDateTime are available in the Java programming to handle the operations related with the date and time problems. Here we need to import the Java package as java.time which is a main application programming interface aka API for date, time, instants, and the time durations. Purpose of the LocalDate, LocalTime and LocalDateTime classes are − java.time.* //It is the process to include all classes java.time.LocalDate //It is the process for LocalDate java.time.LocalDateTime //It is the process ...

The collection class is an enhanced static method to sort the elements from a particular collection of a list or an array. For this process, we can use a tree set also, when we operate on a set of elements as present as the raw set type primarily. The Collections.sort() method is present in the java.util.Collections class, and enables the user to sort the elements from a specific list in an ascending order. The method is an upgraded version of the java.util.Arrays.sort() method class, which is capable to sort the elements from a linked list as well as queue and ... Read More
