创建一个由给定数组的所有其他字符组成的新字符串，并返回它

Question

Need to create a method in which, given a string, a new string will be made and returned formed out of every other character in the original string.

public static String everyOther(String str) {
    String result = "";
    for (int i=0; i<A.length; i+=2){ 
        result = result + str.charAt(i);
    }
    System.out.println(result);

    return result;
}

public static void main(String[] args) {
    String G = "abcdefghijklmnopqrstuvwxyz";
    System.out.println(everyOther(G));
}

Answer 1

Your everyOther method should read

public static String everyOther(String str) {
    String result = "";
    for (int i=0; i < str.length(); i+=2){ 
        result += str.charAt(i);
    }
    return result;
}

Your for loop was slightly off (see my comment on OP), and there is no need to print out your result ehre as you do that in your main function - unless ofcourse you wanted to print it out twice
