Given String str. How do you find the length of the string?

• Use a for loop to count the elements

• str.length;

• str.length();

• str[0].length();

Given and array of 7 integers called nums. How do you access the LAST element?

• nums[7]

• nums[nums.length] - 1

• nums[nums.length - 1]

Which of these correctly assigns initializes a max so that the max value in an array can be found?

• int max = 0;

• int max = Integer.MAX_VALUE;

• int max = Integer.MIN_VALUE;

How do you find the sum in an array?

Given

int sum = 0;

int [] nums = {1,2,23,4,5445,7}

for (i = 0; i < nums.length; i++)

• sum +=nums;

• nums[i] += sum;

• sum += nums[i];

• sum = nums[0]+nums[1];
