looping a new array java code example
Example 1: arrays with for loops
// Search
// Searches through the given array looking
// for the given target. Returns the index number
// of the target if found, or -1 otherwise.
// (classic search-loop example)
public int search(int[] nums, int target) {
// Look at every element
for (int i=0; i<nums.length; i++) {
if (nums[i] == target) {
return i; // return the index where the target is found
}
}
// If we get here, the target was not in the array
return -1;
}
Example 2: arrays with for loops
// Another way to write search that combines
// the "end of array" and "found" logic in one
// while loop. As a matter of style, we prefer
// the above version that uses the standard
// for-all loop.
public int searchNotAsGood(int[] nums, int target) {
int i = 0;
while (i<nums.length && nums[i]!=target) {
i++;
}
// get here either because we found it, or hit end of array
if (i==nums.length) {
return -1;
}
else {
return i;
}
}
