convert the characters of a string into its respective sequential alphabetic number

Question

Eg:
String str="Hey you";

output:
str = 8 5 24 24 15 21

This is the code i've tried and i guess this code might be quite complex.But still am a newbie this is something that i could do at its extreme.

And now coming to the point, i need a statement that swaps the value of character of the given string into the respective number 'j' as you see in the program.

note: got to work at line number 18.

ArrayList<Character> alp=new ArrayList<>();
char x='a';
for(x='a';x<='z';x++) {
alp.add(x);
}
String y="Hi there dood";
String z=y.toLowerCase();
int i,j;
for(i=0;i<26;i++) {
int m=z.charAt(0);
int n;
n=m-'a'+1;
System.out.println(n);
for(j=1;j<=26;j++) {
if(n==j) {
int k='j';
char c=(char)k;
z.charAt(i)='c';
}

Answer 1

● In 18th line : String in java are immutable , so z.charAt(i) = 'c' will not work & give error .
● need of statement to change character to ASCII value (in int)
//2 ways :
1) int ascii =(int) ch;
2) int ascii = ch;
● now lets come to problem solving part [I just thought]
0)make string to lower case
1)make String to char array
2)run a loop over array printing [(ASCII value of each character) - 96] except spaces .

edit : see Rstar code , easy way just like mine of solving it [without even using char array ]☺
