Look at StringBuilder.

final StringBuilder sb = new StringBuilder();
final File[] roots = File.listRoots();  
for(final File root: roots)  
{  
    if (sb.length() > 0)   sb.append("\n");
    sb.append(root);  
}
System.out.println(sb.toString()); // toString() not strictly necessary to println

StringBuilder string = new StringBuilder();
File[] roots = File.listRoots();   
for(File root: roots)  
{  
      string.append(root).append("\n");  
}
System.out.println(string);

String s = Arrays.toString(roots);

  File[] roots = File.listRoots();
  StringBuilder sb = new StringBuilder();

  for(File root: roots)  
  {  
    sb.append(root.getName());  
  }

  String s = sb.toString();
