array numbers for loop code example
Example 1: arrays with for loops
// Find-Max variant -- rather than finding the max value, find the
// *index* of the max value
public int findMaxIndex(int[] nums) {
int maxIndex = 0; // say the 0th element is the biggest
int maxValue = nums[0];
// Look at every element, starting at 1
for (int i=1; i<nums.length; i++) {
if (nums[i] > maxValue) {
maxIndex = i;
maxValue = nums[maxIndex];
}
}
return maxIndex;
}
Example 2: arrays with for loops
// Find-Max
// Given a non-empty array of ints, returns
// the largest int value found in the array.
// (does not work with empty arrays)
public int findMax(int[] nums) {
int maxSoFar = nums[0]; // use nums[0] as the max to start
// Look at every element, starting at 1
for (int i=1; i<nums.length; i++) {
if (nums[i] > maxSoFar) {
maxSoFar = nums[i];
}
}
return maxSoFar;
