In this article, we will learn about the Suppressed Exceptions with Example Java. Thrown exceptions as the name suggests are exceptions that are thrown in code but somehow ignored. If you remember the execution order of the try-catch-finally block and how it throws values or exceptions, you will remember that the exceptions thrown in the […]
Functional Interfaces of Java 8
In this article, we will learn about the functional interfaces of Java 8. Java has always been an object-oriented programming language. This means that Java programming is all about objects (except for a few primitive types for simplicity). Not only do we have functions in Java, but they are also part of Class and we […]
java.util.ConcurrentModificationException
java.util.ConcurrentModificationException is a very familiar exception when working with Java collection classes. Classes in the Java collection are fast, which means that iterator.next() will throw ConcurrentModificationException. ConcurrentModificationExceptions can occur in a multi-threaded and single-threaded Java programming environment. java.util.ConcurrentModificationException Following is the ConcurrentModificationException scenario with an example. The above code will throw exception java.util.ConcurrentModificationException when the code executes […]
Loop to avoid java.util.ConcurrentModificationException
In this article, we will learn about the Loop to avoid java.util.ConcurrentModificationException. When you are in a single-threaded environment and you want your code to support additional objects added to the list. You can do this using a for loop instead of a loop. Therefore notice that I decrease the counter because I am deleting […]
Avoid ConcurrentModificationException in multi-threaded
In this article, we will learn about the Avoid ConcurrentModificationException in multi-threaded. You can convert the list to an array and then iterate over the array. This approach works well for small to medium sized lists, but if the list is large it will severely affect performance.You can lock the list during iteration by placing […]
Difference between Java 7 and Java 8
In this article, we will learn what is the main difference between Java 7 and Java 8 and what are the features of Java 7 and Java 8. Java 7 and its Features The Java 7 was the first major update in the field of programming language since the addition of the Sun Microsystems. The […]
Example of a Java ZIP file folder
Today we’re going to look at a sample Example of a Java ZIP file folder. We will also compress a folder and create a zip file using the Java program. Java ZIP java.util.zip.ZipOutputStream can be used to compress a file in ZIP format. A ZIP file can carry multiple entries and ZipOutputStream uses java.util.zip.ZipEntry to […]
Java Inner Class
The inner Java class defines the body of another class. The inner class can define as private, public, secure, or with standard access, while an outer class can only have public or standard access. Therefore the Java nested classes have two types. 1. Static nested class If the nested class is static then it is […]
Java8 Core API Improvements
In this article, we will learn about the Java8 Core API Improvements. A few different API improvements that might come in handy includes Static ThreadLocal with Initial method (Provider provider) to easily create instances. The user interface improves with many standard and static modes for natural layout, inverted layout, etc. Therefore min(), max(), and sum() […]
Java ThreadLocal example
Java Thread Local use to generate local thread settings. We know that all threads on an object share its variable, so the variable thread is not safe. We can also use sync to protect the variable. Alternatively, we can use thread local variables to prevent synchronization and we learn about the Java ThreadLocal example. Each […]
