What is a constructor in Java?
Many students want to know what is a constructor in Java. You will come across plenty of information online. However, if you wish to understand Java constructor in a simple and lucid language, you’ve come to the right place. We’ve made Java simpler for you to understand, comprehend and even use practically on the computer.
A Java constructor refers to a series of codes, which is essential to specify the state of objects in the class. It helps in executing instance variables in that class. The only use of java constructor is to specify a particular task to data fields in the class. It can perform any action but it’s primarily responsible for managing or defining class in instance variables.

Constructor Overloading in Java—Meaning and Significance
In its simple terms, a Java constructor does actually refer to a ‘without return-type’ method. But it can also be overloaded to imitate a normal Java method.
Under constructor overloading in Java, multiple overloaders are used, each having a separate parameter list. Once executed, each constructor works and performs a different function. Compilers are used within the syntax to define their work and types.

What is the Difference between Java Method and Java Constructor?
Primarily, Java method always has a return type but a constructor doesn’t. Java method may or may not have the same name as the class, but the name of a constructor must be the same as its class and finally, Java method reflects how an object works, but a constructor just initialises the object.
Constructor in Java is a significant topic. It holds the key to mastering the Java language and performing various functions on it. Java constructor in many cases works exactly the same as a normal Java method. If you start using Java constructor regularly for your programming or Java projects, you will easily understand everything about it.
Always remember that in many cases, Java method and Java constructor work similarly; however, they are not completely same all the time.
