1. Use Java code to write a function that converts an array of Strings to an array of integers. Example:

arr = {"40", "50", "70"}

to arr = {40,50,70}.

Solution.

public int[] convertArray(String[] strArr) {
    int[] iArray = new int[strArr.length];
    for(int i = 0; i < strArr.length; i++) {
        iArray[i] = Integer.parseInt(strArr[i]);
    }
    return iArray;
