Please masters to help write an algorithm !!

I don’t want to standardize it, I just want it to be editable, and test it. I’ve typed it out with you, wrong.

class T
{
static String str34[] = {"0", "1", "2", "3", "4", "5", "6", "7", "8", "9",
                "A", "B", "C", "D", "E", "F", "G", "H", "J", "K", "L", "M",
                "N", "P", "Q", "R", "S", "T", "U", "V", "W", "X", "Y", "Z" };
public static void main(String[] args)
{
System.out.println("Hello World!");
function(4,34,"");
}
public static void function(int p,int d,String arg){
if(p==0){System.out.println(arg); return;}
for(int i=0;i<d;i++){
arg+=str34[i];
function(p-1,d,arg);
arg=arg.substring(0,arg.length()-1);}
}

I have a question, I'm sorry, I am also a novice, I will take a look

Wow, the big brother upstairs has a good history. At such a high level, please explain the code above, thank you very much!

The above is good, take a look

Brother, an exception was thrown.

This is good, I debugged it and it ran all the time
public class Test1 {

/**
* @param args
*/
public static void main(String[] args) {
// TODO automatically generates method stubs
String[] strAr= {"1","2","3","4","5","6","7","8","9","A","B", "C","D","E","F","G","H","J","K","L","M","N","P","Q ","R","S","T","U","V","W","X","Y","Z"};
String num = "0000";
long s=0;
int genum=0, shinum=0, bainum=0, qiannum=0;
int length=strAr.length;
while(true){
System.out.println(s+":"+num);
s++;
genum++;
if(genum<=length){
num=num.substring(0,3)+strAr[genum-1];
}else{
genum=0;
shinum++;
if(shinum<=length){
num=num.substring(0,2)+strAr[shinum-1]+"0";
}else{
shinum=0;
bainum++;
if(bainum<=length){
num=num.substring(0,1)+strAr[bainum-1]+"00";

bainum=0;

Isn't it alright?
