Hi, how is it possible that: as method2() is non-static, method1() cannot use it => method1() needs to be static as well. So why in method2() that is changed to static I can call non-static method3()? What exactly 'new Solution().method3()' works like? Could anybody explain it to me in an easy way, please?
public static void method1() {

    public static void method2() {
        new Solution().method3();

    public void method3() {

    public void method4() {
