三种字符数组合并的方法
public static String[] getOneArray() {
String[] a = { "0", "1", "2" };
String[] b = { "0", "1", "2" };
String[] c = new String[a.length + b.length];
for (int j = 0; j < a.length; ++j) {
c[j] = a[j];
}
for (int j = 0; j < b.length; ++j) {
c[a.length + j] = b[j];
}
return c;
}
public static Object[] getTwoArray() {
String[] a = { "0", "1", "2" };

List aL = Arrays.asList(a);
List bL = Arrays.asList(b);
List resultList = new ArrayList();
resultList.addAll(aL);
resultList.addAll(bL);
Object[] result = resultList.toArray();
return result;
}
public static String[] getThreeArray() {
String[] a = { "0", "1", "2", "3" };
