The only way to call a non-static method from a static method is to have an instance of the class containing the non-static method.
class A
{
void method() { } } class Demo
{
static void method2() { A a=new A(); a.method(); } /*
void method3() { A a=new A(); a.method(); } */
public static void main(String args[]) { A a=new A(); /*an instance of the class is created to access non-static method from a static method */ a.method(); method2(); /*method3();it will show error non-static method can not be accessed from a static method*/ } }
