int arr[] = new int[10]; for(int i=0;i<10;i++){ arr[i]=s.nextInt(); } Arrays.sort(arr); System.out.println(" "+Arrays.toString(arr)); my input is :
98 7 6 5 4 32 14 5 1 7
my output is :
[1, 4, 5, 5, 6, 7, 7, 14, 32, 98]
but i want to print my output as sorted number only but not with [ ] and commas what would be the required solution
Just loop over the array, and print each number.
for (int i: arr) { System.out.print(i); System.out.print(" "); } System.out.println(); 
i is not the index, but the element of the collection you are iterating over. This is different from for (int i=0; i<10; i++)
Use replaceAll to replace [ and ] with empty string:
System.out.println(" " + Arrays.toString(arr).replaceAll("[\\[|\\]]", "")); One solution is to iterate over the array and print the desired string. Another solution is just using substring as following:
String result = Arrays.toString(arr); System.out.println(" "+result.substring(1, result.length()-1)); By iterating also you can get this result as following:
for (int i=0;i<arr.length;i++){ System.out.print(arr[i] + " "); } Or using regex, you can replace first and last characters as following:
System.out.println(" " + Arrays.toString(arr).replaceAll("^.|.$", "")); You can also use StringUtils(commons-lang) which is null safe:
StringUtils.substringBetween(Arrays.toString(arr), "[", "]"); 
System.out.println(Stream.of(arr).sorted( ).map( String::valueOf ).collect( Collectors.joining( " " ) ));
