Printing Java Collections Nicely (toString Doesn't Return Pretty Output)
I wish to print a Stack<Integer> object as nicely as the Eclipse debugger does (i.e. [1,2,3...]) but printing it with out = "output:" + stack doesn't return this nice result.
Just to clarify, I'm talking about Java's built-in collection so I can't override its toString().
How can I get a nice printable version of the stack?
Solution 1:
You could convert it to an array and then print that out with Arrays.toString(Object[]):
System.out.println(Arrays.toString(stack.toArray()));
Solution 2:
String.join(",", yourIterable);
