Consider the following method:

public static void dostuff (int a[], int b) {
if (/* missing code */) {
for (int i = b; i < a. length; i++) {
a[i] = a[i] * 2;
}
}
}

what could be used to replace / *missing code* / so that there is no out of bounds exception?

a. b < a. length
b. b > 0 b < a. length
c. b > 0 & & b < = a. length
d. b > = 0 || b < a. length
e. b > = 0 & & b < a. length

e. b >= 0 && b < a.length

Explanation:

Array indices in java begin at 0 and go up to number n-1, where n is the length of the array.

Note: a.length returns the length of the array. We can assume the array length to be n for this case.

Option a is incorrect since b can be less than 0, which causes an out of bounds exception.

Option b is incorrect because two comparison statements are separated by a boolean operator, therefore it will cause a syntax error.

Option c is incorrect because if b = a.length, this means that i will begin from nth index of the array, where as array indices only range from 0 to n-1 as mentioned earlier.

Option d is incorrect because it uses the || (or) operator. This means that only one condition of the two given has to be true. Suppose if b is negative, this will cause b >= 0 to be false. However, since array length can never be negative, b < a.length will always be True, hence we can have an out of bounds exception in this case.

f7 should open the spelling and grammer dialog box

he could use bold or bigger text just a suggestion.
