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*/     } 

}
