In Java, if we keenly observe a constructor pretty much looks like a method, So let's see the major differences between a constructor and a method.

Point.java

package DevLearn.src;

public class Point {
    public int x;
    public int y;
    
    // a constructor
    public Point(int a, int b) {
        x = a;
        y = b;
    }
    
    // a method
    public void setPoint(int a, int b) {
    		x = a;
    		y = b;
    }
}

So as we can see from the example,
- constructor would always have same name as the class & has no return type. The first letter should always be capitalized
- Where as the method needs to have the return type.
- Also the constructor can be called only while initializing the object where as we are free to call a method as many times as we would like
