Answer 1

public class Dir
{
public static void main(String args [])
{
int a=10,b=20;
if(10<20)
{
System.out.println("first statement");
System.out.println("second statement");
}
else
{
System.out.println("else statement");
}
// till this all was right but after this you forgot to close the class and function...
}
}// End of class Dir
// Now it is closed...
// Now your Mz class will start...
class Mz
{
// In question there is no function method...
// It should be there...
public static void main(String args [])
{
int h=30;
System.out.println(h);
}
}// End of class Mz
