Java error: Cannot be applied to given types-CodePudding

So I'm quite new to Java and this is the first time I'm working with objects. Could you help me out with why this piece of code doesn't work?

public class Object
{
    String a1;
    String[] a2;
    int a3;
    double a4;
    long a5;
}

And here is the main class:

public class Main
{
    public static void main(String[] args)
    {
        Object obj1 = new Object("example text", new String[] {"some", "more", "examples", "here"}, 1, 1.0);
    }
}

Error message:

java: constructor Object in class Object cannot be applied to given types; required: no arguments found: java.lang.String,java.lang.String[],int,double reason: actual and formal argument lists differ in length

CodePudding user response：

You must declare a constructor for your Object class inside it as:

public class Object {
    String a1;
    String[] a2;
    int a3;
    double a4;
    long a5;

    public Object(String example_text, String[] strings, int i, double v) {
    }
}

And another important thing is that Object is a predefined class in Java, so you should use full package name of your own Object class in main method:

public class Main
{
    public static void main(String[] args)
    {
        Object obj1 = new path.to.Object("example text", new String[] {"some", "more", "examples", "here"}, 1, 1.0);
    }
}

You should change the name of your class, since Java already has a class name Object or add a constructor for your Class. Use for example the name MyObject.java
