为什么我的数组包含所有空值？ [英] Why does my array contain all nulls?

问题描述

为什么我的数组包含所有空值？



System.out.println（loo）; - >这将正确显示数组中的内容

System.out.println（tokFix [i]）; - >虽然这将显示所有null的

Why does my array contain all nulls?

System.out.println(loo); -> This will show what's inside the array properly
System.out.println(tokFix[i]); -> While this will show all null's

public static String[] parseFixMsg(String fixMsg1,String fixMsg2){
    int i = 0;
    int size = getArraySize(fixMsg1);
    String[] tokFix = new String[size];
    StringTokenizer st = new StringTokenizer(fixMsg2,(Character.toString((char)01))+"]");
    st.nextToken();


    while (st.hasMoreTokens()) {

        tokFix[i] = st.nextToken();
        String loo = tokFix[i];
        i++;
        <big>System.out.println(loo);
        System.out.println(tokFix[i]); </big>       }
    return tokFix;
}


public static int getArraySize(String fixMsg){
    int size = 1;
     StringTokenizer st = new StringTokenizer(fixMsg,(Character.toString((char)01))+"]");


     st.nextToken();
        while (st.hasMoreTokens()) {
            st.nextToken();
            size+=1;
        }
        return size;
}

推荐答案

你增加 i 之前检查。当然下一个项目是空的，你还没有填充它。

You incremented i before checking. Of course the next item is empty, you haven't populated it yet.
