34．编写2个接口：InterfaceA和InterfaceB；在接口InterfaceA中有个方法void printCapitalLetter()；在接口InterfaceB中有个方法void printLowercaseLetter()；然 后写一个类Print实现接口InterfaceA和InterfaceB，要求printCapitalLetter()方法 实现输出大写英文字母表的功能，

//接口InterfaceA

package jieKou;

public interface IInterfaceA {

void printCapitalLetter();

}

//接口InterfaceB

package jieKou;

public interface IInterfaceB {

void printLowercaseLetter();

}

//类print

package jieKou;

public class Print implements IInterfaceA, IInterfaceB {

@Override
public void printLowercaseLetter() {
	System.out.println("abc");

}

@Override
public void printCapitalLetter() {
	System.out.println("ABC");

}

}

//主类E

package jieKou;

public class E {

public static void main(String[] args) {
	Print p=new Print();
	IInterfaceA a=p;
	IInterfaceB b=p;
	a.printCapitalLetter();
	b.printLowercaseLetter();

}

}
