关于java中数组的问题

Question

现有个数组

String purview = "1,1,0,1,0,0,0,0,1,1,1,0";
Sting[] str = purview.split(",");

我如何把这数组中为“1”的index放到另外一个数组中？向各位请教下

Answer 1

[code="java"]import java.util.ArrayList;
import java.util.List;

public class Test {

public static void main(String[] args) {
    String purview = "1,1,0,1,0,0,0,0,1,1,1,0";
    String[] strs = purview.split(",");

    List strLocs = new ArrayList();

    int loop = 0;
    for (String str : strs) {
        loop++;
        if (str.trim().equals("1")) {
            strLocs.add(loop);
        }
    }

    Object[] locArrays = strLocs.toArray();

    for (Object loc : locArrays) {
        System.out.print("  " + loc);
    }
}
