Java 生成字母数字序列

我在根据给定的数字生成数字时遇到问题。实际上，我必须得到像

DAA001，DAA002这样的系列，DAA003……DAA999

一旦

DA

序列中填充了

DAA999

它就必须生成

DAB001…DAB999

，一旦序列

DAB

中填充了

DAB999

它就必须生成

DAC001

到

DAC999

，就像

dadz001到dad999

一样

这是我的密码，请帮我

String start="DA";
String driv[]={"A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"};
String PrNumber="";
int  count=0;
if(driverprId<=999){
    count=0;
    start=start+driv[count];

    if(driverprId>=1&&driverprId<10){
        PrNumber=start+"00"+driverprId;
    }

    if(driverprId>=10&&driverprId<100){
        PrNumber=start+"0"+driverprId;
    }

    if(driverprId>=100&&driverprId<=999){
        PrNumber=start+driverprId;
    }
}

if(driverprId>999){
}

return PrNumber;

String start=“DA”；
字符串driv[]={“A”、“B”、“C”、“D”、“E”、“F”、“G”、“H”、“I”、“J”、“K”、“L”、“M”、“N”、“O”、“P”、“Q”、“R”、“S”、“T”、“U”、“V”、“W”、“X”、“Y”、“Z”}；
字符串PrNumber=“”；
整数计数=0；
如果（driverprId=1&&driverprId=10&&driverprId=100&&driverprId999）{
}
返回PRN号码；

尝试以下方法：

int counter = 0;
for (int i=0;i<driv.length;i++) {//for each alphabet
    for (int j=0;j<999;j++) { //iterate till 999
         start=start+driv[i];//keep using DA A if i is 0 for 999 times
         ...

        if (counter == number) {//number is like number of cells you need
            return;
        }
        counter++;
    }
}

int计数器=0；
对于（inti=0；i类似的东西应该可以工作：

String start="DA";
String driv[]={"A","B","C","D","E","F","G","H","I","J","K","L","M","N","O","P","Q","R","S","T","U","V","W","X","Y","Z"};
for(int i = 0; i < driv.length; i++) {
    for(int j = 1; j <= 999; j++) { 
        String numbers;
        if (j / 10 < 1) {
            numbers = "00" + j;
        } else if (j / 10 < 10) {
             numbers = "0" + j;
        } else {
             numbers = "" + j;
        }
        PrNumber = start + driv[i] + numbers;
}

String start=“DA”；
字符串driv[]={“A”、“B”、“C”、“D”、“E”、“F”、“G”、“H”、“I”、“J”、“K”、“L”、“M”、“N”、“O”、“P”、“Q”、“R”、“S”、“T”、“U”、“V”、“W”、“X”、“Y”、“Z”}；
对于（int i=0；i对于（int j=1；j请使用if条件来帮助我，如果我使用for循环，我肯定会遇到问题，我不想一次生成所有记录，假设如果我给134，它必须生成结果为DAA134，如果我给26134，它应该打印结果为DAB134，这就是它，没有迭代…@user3528870查看我编辑的答案。数字是134 or 26134，我们正在比较计数器。请使用if条件帮助我，如果我使用for循环，我肯定会遇到问题，我不想一次生成所有记录，假设如果我给134，它必须生成结果为DAA134，如果我给26134，它应该将结果打印为DAB134，这就是它，没有迭代。。。。
if (driverprId / 10 < 1) {
        numbers = "00" + j;
    } else if (driverprId / 10 < 10) {
         numbers = "0" + j;
    } else {
         numbers = "" + j;
    }
