Can someone tell what's wrong with this code?

Question

//Remove the given age below and enter your age.
public class Program
{
public static void main(String[] args) {
int age=19;
if(age == 16)
if(age == 17)
{
System.out.println("Get your provisional license");
if(age < 15){
System.out.println("Too young!");
if(age == 15){
System.out.println("Get learner's license");
if(age >= 18){
System.out.println("Congrats! Get driver's license.");
}
}
}
}

}
}

Answer 1

age=19 and if condition if(age==16) becomes false so it directly goes to else part but you dont have else. No other statements gets executed because all next statements is in
if(age==16)
{
here..
}
Hence there no output..
