how to store a byte [] into a single variable in android/java -

i have string str = "admin:admin"

i want convert in ascii.

i have tried str.getbyte("us-ascii"); returning me byte[] array (i.e [97, 100, 109, 105, 110, 58, 97, 100, 109, 105, 110]). want ascii value in single string variable. how can this.

simple want string strascii = "971001091051105897100109105110"

is possible?

i tried this

stringbuilder builder = new stringbuilder(); (int i=0; i<=b.length; i++) { builder.append(b); } string result = builder.tostring();

but returning me this

[b@405666e0[b@405666e0[b@405666e0[b@405666e0[b@405666e0[b@405666e0[b@405666e0[b@405666e0[b@405666e0[b@405666e0[b@405666e0[b@405666e0

what this?

try looping stringbuilder:

stringbuilder builder = new stringbuilder(); (byte b : arr) { builder.append(b); } string result = builder.tostring();

you could, of course, same thing string concatenation, using stringbuilder explicitly faster lots of little appends.
