In Javascript I would do it like that:
const _data = new Uint8Array([0, 1, 2, 4, 5, 6, 7, 8, 9, 77, 100]);
const s = '[' + _data.join(',') + ']';
console.log(s);
> [0,1,2,4,5,6,7,8,9,77,100]
Added the solution from SomeDude:
byte[] b = new byte[]{1,2,3,4,5,77};
s = Arrays.toString(b);
System.out.println(s);
> [1, 2, 3, 4, 5, 77]
The simplest method:
byte[] b = new byte[]{1,2,3,4,5};
String s = Arrays.toString(b);
Or
StringBuilder sb = new StringBuilder("[");
for ( int i = 0; i < b.length; i++ ) sb.append(String.valueOf(b[i]) + ",");
sb.append("]");
String s = sb.toString();
Or with streams if you have an array of boxed bytes like:
Byte[] B = new Byte[]{1,2,3,4,5};
String s = "[" + Stream.of(B).map(Object::toString).collect(Collectors.joining(",")) + "]";
System.out.println(s);
This may not be the best way, but this is a way:
final var data = new byte[] { 0, 1, 2, 4, 5, 6, 7, 8, 9, 77, 100 };
final var s = "[" +
IntStream.range(0, data.length)
.mapToObj(i -> Byte.toString(data[i]))
.collect(Collectors.joining(",")) +
"]";
System.out.println(s);
