Question

Please help me to solve this:

I have two strings for email-id and password like

String name = "[e-mail]";
String pass = "abc";

I encode these two into Base64 string like

String encoded_name = new String(Base64.encode(name.getBytes(), 0));
String encoded_pass = new String(Base64.encode(pass.getBytes(), 0));

and I need to concatenate these two encoded strings with space like

String merge = encoded_name + " " + encoded_pass;

I checked this string in console by

System.out.print("Concatenate string= " + merge);

but in console I am getting result in two lines like this

11-18 00:25:29.898: INFO/System.out(1244): Merge= eHl6QGdtYWlsLmNvbQ==
11-18 00:25:29.908: INFO/System.out(1244):  YWJj

Why is this happing the result is unexpected for me why it is not printing in a single line. please help me to solve this.

Thanks

You should use the NO_WRAP flag as described in the Docs, the Base64 class will not add additional newlines.

NO_WRAP: Encoder flag bit to omit all line terminators (i.e., the output will be on one long line).

So change your lines to the following:

String encoded_name = new String(Base64.encode(name.getBytes(), Base64.NO_WRAP));
String encoded_pass = new String(Base64.encode(pass.getBytes(), Base64.NO_WRAP));

This will output the following:

11-17 19:16:51.283: INFO/System.out(354): Concatenate string= eHl6QGdtYWlsLmNvbQ== YWJj
