Question

(From Lesson 17 of Blue Pelican Java)

Use the following code for problems 1 – 15. In each problem state what’s printed.


String s = “Lucky hockey puck”;


String m = “uck”;


int j = 6, z = 99;





1. int k = s.indexOf(m);

System.out.println(k);




2. int k = s.indexOf(“uck”, j);

System.out.println(k);





3. int k = s.indexOf(‘c’);

System.out.println(k);





4. String str = s.replace(‘o’, ‘p’);

System.out.println(str);




5. int k = s.lastIndexOf(m, j + 3);

System.out.println(k);




6. char p = s.charAt(7);

System.out.println(p);







7. int k = s.indexOf(z);

System.out.println(k);




8. int k = s.lastIndexOf(m);

System.out.println(k);




9. int k = s.indexOf(‘y’, j);

System.out.println(k);




10. char p = s.charAt(z - 90);

System.out.println(p);




11. int k = s.indexOf(m,15);

System.out.println(k);




12. int k = s.indexOf(z + 2, 4);

System.out.println(k);




13. int k = s.lastIndexOf(‘h’);

System.out.println(k);




14. int k = s.lastIndexOf(121);

System.out.println(k);







15. String str = s.replace(‘y’, ‘A’);

System.out.println(str);
