question 58)
you have these files in the same directory. what will happen when you attempt to compile and run class1.java if you have not already compiled base.java
//base.java
package base;
class base{
protected void amethod(){
system.out.println('amethod');
}//end of amethod
}//end of class base
package class1;
//class1.java
public class class1 extends base{
public static void main(string argv[]){
base b = new base();
b.amethod();
}//end of main
}//end of class1
1) compile error: methods in base not found
2) compile error: unable to access protected method in base class
3) compilation followed by the output 'amethod'
4)compile error: superclass class1.base of class class1.class1 not found

class base{
private void amethod(int ibase){
system.out.println('base.amethod');
