In the Test.java source file, which are correct class definitions?

A. public class test {

public int x = 0;

public test(int x)

{

this.x = x;

}

}

B. public class Test{

public int x=0;

public Test(int x) {

this.x = x;

}

}

C. public class Test extends T1, T2 {

public int x = 0;

public Test (int x) {

this.x = x;

}

}

D. public class Test extends T1{

public int x=0;

public Test(int x){

this.x = x;

}

}

E. protected class Test extends T2{

public int x=0;

public Test(int x){

this.x=x;

}

}

Explanation:

In the Test.java source file the class name should be Test, not test, for it is case-sensitive in Java. One class should have not more than one superclass. The protected modifier can not be put in front of the class.
