adding arrays using for loop in java code example

Example 1: arrays with for loops

int findSmallest(int[] values) {
  int minIndex = 0;  // start with 0th element as min
  for (int i=1; i<values.length; i++) {
    if (values[i] < values[minIndex]) {
      minIndex = i;
    }
  }
  return minIndex;
}

Example 2: arrays with for loops

// Given an array of booleans representing a series
// of coin tosses (true=heads, false=tails),
// returns true if the array contains anywhere within it
// a string of 10 heads in a row.
// (example of a search loop)
public boolean searchHeads(boolean[] heads) {
  int streak = 0;     // count the streak of heads in a row
  
  for (int i=0; i<heads.length; i++) {
    if (heads[i]) {   // heads : increment streak
      streak++;
      if (streak == 10) {
        return true;  // found it!
      }
    }
    else {            // tails : streak is broken
      streak = 0;
    }
  }
  
  // If we get here, there was no streak of 10
  return false;
}
