Question

Determine whether the following statements are true or false. An instance variable can be accessed in a static method. An array is an object in Java. Instance methods can be called through the class name. If a local variable has the same name as an instance variable, the local variable will be used in the method. You cannot change the length of an array once it has been created. Determine the value of the following method calls. String str = "World Wide Web"; str.substring(6,10) str.indexOf("W") str.substring(11) str.charAt(7) str.substring(0, 6) What will be the result of each method call? String s5 = "coffee"; String s6 = "COFFEE"; s5.equals(s6) s5.equalsIgnoreCase(s6) s5.equals(s6.toLowerCase()) s6.compareTo(s5) s5.compareTo(s6.toLowerCase())
