PublicConstructor - Intellij Community

Reports public constructors.

Some coding standards discourage the use of public constructors and recommend static factory methods instead. This way the implementation can be swapped out without affecting the call sites.

Example:

class Test {
    private String name;

    public Test(String name) {
        this.name = name;
    }

    public void test() {
        System.out.println(name);
    }

    public static void main(String[] args) {
        new Test("str").test();
    }
  }

After quick-fix is applied:

class Test {
    private String name;

    private Test(String name) {
        this.name = name;
    }

    public static Test getInstance(String name) {
        return new Test(name);
    }

    public void test() {
        System.out.println(name);
    }

    public static void main(String[] args) {
        getInstance("str").test();
    }
  }
