In Java, An array is a collection of items of the same type with a fixed number of items. It contains data items that are all the identical. In other ways we can say that it consists of homogeneous data items. The length of the array is determined when it is created. Each item in…
In Java, method overloading happens when the names of two methods are the same but the arguments are different. Two methods with the same name but different parameters are permitted in Java, and these methods are referred to as overloaded methods. We must verify method names, which must be the same, and parameters, which must…
Stack memory and heap memory (Stack Vs Heap) are two crucial parts of programming that help us ensure that our application makes efficient use of memory. We’ll talk about which information stack stores and which information stack stores and We’ll go through the difference between stack and heap also in depth in this section. Memory…
In Top Java Programs for Coder article we have listed here programs to develop the logic of programming of the coder, programmer, developer. Let’s start with the basic Java programs and then we will gradually increase the level of programming. Display numbers from 1 to 10 using infinite for loop. We can form the infinite…
In Java, by using exception handling technique in java we handle runtime errors to maintain the normal flow of the program and we avoid abnormal termination. In exception handling we define some alternative way by which we make the program to maintain the normal flow of the program even if there is an exception in…
Thread synchronization prevents another thread from accessing an item that is currently being worked on by another thread. If thread T1 is working on object O1, we prohibit thread T2 from accessing object O1 during the thread synchronization procedure. Thread synchronization is all this is. The “synchronized” modifier is used to establish synchronization. It only…
A multithreading in Java is a concept where we split a program into two or more sub-programs and execute them at the same time. If we take real world example, we can assume that there is a task which we divide into sub tasks and assign them to different people for execution independently and simultaneously….
A Java loop is used to repeat a section of code several times. Sometimes we know how many iterations there are, and sometimes we don’t. For instance, if you want to display numbers from 1 to 10, you can use a loop, and if you want to print anything several times, you can also use…
Both classes are mutable in nature, so you can use them when you need to do a lot of modifications to a string of characters. In this section we will see the difference between StringBuffer and StringBuilder. What are StringBuffer and StringBuilder? StringBuffer in Java The StringBuffer class in Java is mutable and there are…

There are several steps we use to establish connectivity with the database in Java. In this section we will go through the steps of Java Database Connectivity in details. Let’s first get the basic idea about the database driver and then we will know the steps of database connectivity with syntax and example. What is…
