Hi there,
Explanation 4: Can you give me a sample code for an interface with a body?

Thanks.

[admin]

Code: Select all

interface I1{

 int X = 10;
}

interface I2{
    int X = 20;
}

interface I extends I1, I2{
    int Y = X; //Error because of ambiguous reference to X
    int Z = I1.X; //Valid
}

Code: Select all

interface I1{

 int X = 10;
}

interface I2{
    int X = 20;
}

interface I extends I1, I2{
    int Y = X; //Error because of ambiguous reference to X
    int Z = I1.X; //Valid
}

Thank you

In Java 8 intarfaces may contain static methods and default methods. I thought that static methods were also available in earlier versions of Java

4. Fields of an interface may be declared as transient or volatile but not synchronized.
Is it possible, to specify the "volatile" for the public statics final variable?
What's the point? Flows would not be able to change the final variable.

[admin]

That's right. Volatile doesn't make sense for final variables because such variables do not change.

Thanks for your reply.
