publicstatic voidmain(String[] args){

Random gen =new Random();

int keyLength, maxLength = 26, minLength=5;

boolean[]used = new boolean[maxLength];

String key = "";

int i,j,usedcount=0;

int creationCount =0;

for(i=0;i<maxLength;i++){

used[i]=false;

//creationCount++;

}

keyLength =gen.nextInt(maxLength-minLength)+minLength;

while(usedcount<keyLength){

j=gen.nextInt(maxLength);

if(!used[j]){
