How can I convert the numbers of ASCII to character by easier way?

[Raghad94]

Hi

I'm a beginner on Java

so I hope you guys can help me

int a1 = str.charAt(0)+1;
int a2 = str.charAt(1)+1;
int a3 = str.charAt(2)+1;
int a4 = str.charAt(3)+1;
 
 
System.out.print("output :");
System.out.print((char)a1);
System.out.print((char)a2);
System.out.print((char)a3);
System.out.println((char)a4);
 

I want to know how to write (char)a1,(char)a2 ... (char)a4 in one System.out.print
also I want to know how can I write (char)a1 outside of the System.out.print, I mean
???? = (char)a1

please help :)

Answering your first question, I think you can do this:

System.out.print( (char)a1 + ", " + (char)a2 + ", " + (char)a3 + ", " + (char)a4 )

Regarding your second question, you want to assign (char)a1 to a char variable?

Lines 1..4 can be done like this:

anArray = new int[4];
for (int x=1; x<=4; x++) {
  int a[x] = str.charAt(x-1)+1;
}
 

this seems longer, but when you do it more than 4 times it gets shorter (than the original way) ;)

Also your lines 8..11 can be done insize a 'for'-loop.
