Question

What is the Java output?

Part One:

class Driver {
  public static void main(String[] args) {
    int a = 5;
    int b = 3;

    if (a < b || a * 2 < b)
      System.out.print(a - b);

    System.out.print(b + a);
  }
}

Part Two:

class Driver {
  public static void main(String[] args) {
    int a = 5;
    int b = 8;

    if (a < b)
      if (a * 2 < b)
        System.out.print("foo");
      else
        System.out.print("bar");
    else
      System.out.print("buz");
  }
}

Answer 1

part one:

class Driver {
public static void main(String[] args)
{
int a = 5; int b = 3;
if (a < b || a * 2 < b) //5<3 || 5*2<3 => false || false => a-b not executed
System.out.print(a - b);
  
System.out.print(b + a);
  
}
  
}

output:

1.li Result $javac Driver.java $java -Xmx128M -Xms16M Driver

part two:

public class Driver {
public static void main(String[] args)
{
int a = 5; int b = 8;
if (a < b) //5<8 true
if (a * 2 < b) //5*2<8 => false so else executed
System.out.print("foo");
else System.out.print("bar");
else System.out.print("buz");
  
}
  
}

I.l. Result $javac Driver.java $java -Xmx128M -Xms16M Driver bar

Output:
