The error message “no suitable constructor was found” typically occurs when you try to create an object of a class, but there is no constructor available with the specified parameters. Constructors are special methods used to initialize objects of a class.
To understand this error in more detail, let’s consider an example. Suppose we have a class “Person” with two properties: name and age. We want to create an object of this class and initialize it with a name and age value. Therefore, we create a constructor with two parameters:
class Person {
String name;
int age;
public Person(String personName, int personAge) {
name = personName;
age = personAge;
}
}
// Creating an object and initializing it
Person person = new Person("John", 25);
In the above example, the constructor “Person(String personName, int personAge)” takes two parameters – personName and personAge. These parameters are used to initialize the properties of the object.
If you try to create an object of the Person class without passing any arguments or with different arguments, the error “no suitable constructor was found” will occur. For example:
Person person = new Person(); // Error: no suitable constructor found
// or
Person person = new Person("John"); // Error: no suitable constructor found
In the above cases, since there is no constructor available without any arguments or with only one argument, the error is thrown.
To fix this error, you need to make sure that you are calling the constructor with the correct number and types of arguments that match the defined constructor in the class.
