/*
* Stitch the array into a string
*/
public class StringBufferTest2 {
public static void Main (string[] args) {
Define an array
Int[] arr = {44, 33, 55, 11, 22};


Defining features
Mode 1: Use String to stitch the way
String S1 = arraytostring (arr);
System.out.println ("S1:" + S1);


Way 2: Use StringBuffer to do the stitching way
String s2 = arrayToString2 (arr);
System.out.println ("s2:" + s2);
}


The way to do stitching with StringBuffer
public static String arrayToString2 (int[] arr) {
StringBuffer sb = new StringBuffer ();


Sb.append ("[");
for (int x = 0; x < arr.length; × x + +) {
if (x = = arr.length-1) {
Sb.append (Arr[x]);
} else {
Sb.append (Arr[x]). Append (",");
}
}
Sb.append ("]");


return sb.tostring ();
}


Use String to stitch the way
public static String arraytostring (int[] arr) {
String s = "";


s + = "[";
for (int x = 0; x < arr.length; × x + +) {
if (x = = arr.length-1) {
s + = arr[x];
} else {
s + = arr[x];
s + = ",";
}
}
s + = "]";


return s;
}
}
