如何创建具有多个返回类型的接口方法

public interface MultiReturnTypeInterface {
    public String getStringValue();
    public int getIntValue();
    public boolean getBooleanValue();
}

public class MultiReturnTypeClass implements MultiReturnTypeInterface {
    @Override
    public String getStringValue() {
        return "Hello, World!";
    }

    @Override
    public int getIntValue() {
        return 42;
    }

    @Override
    public boolean getBooleanValue() {
        return true;
    }
}

public class Main {
    public static void main(String[] args) {
        MultiReturnTypeInterface instance = new MultiReturnTypeClass();
        
        String stringValue = instance.getStringValue();
        int intValue = instance.getIntValue();
        boolean booleanValue = instance.getBooleanValue();
        
        System.out.println("String Value: " + stringValue);
        System.out.println("Int Value: " + intValue);
        System.out.println("Boolean Value: " + booleanValue);
    }
}
