Program is given below

{


int i,j;


x c= new x();


for(i=0;i%26lt;3;i++)


for(j=0;j%26lt;4;j++)


System.out.println("s="+c.S[i][j]);


fun(c);


}


void fun(x c)


{


int i,j;


for(i=0;i%26lt;3;i++)


for(j=0;j%26lt;4;j++)


System.out.println("s_fun="+c.S[i][j]);


}


}


class x{


long S[][]={


{1,2,3,4},


{5,6,7,8},


{9,10,11,12}


};


}

man o man........


its simple....make fun static and the error wuld disappear...


reason: static funcs can only call static funcs within the same class..here main is static whereas fun is nonstatic....





sometimes we do make small mistakes!


good luck

Reply:define fun as static void fun(x c). You're calling fun from a static function (main). fun is not part of a class definition.
