tabang in Java. tabang!

charAt(int index) - Returns the char value at the specified index.


String myString = "My String";
System.out.println("Character at index 4: "+myString.charAt(4));
Output: Character at index 4: t

     case '}':
		if (isBrace(stack.peek().toString().charAt(0)))
		{
		     stack.pop();
		}
		break;

Atong sabtun ang logic, english-bisaya..
Kung ang character sa index 0 kay isBrace(c == '{' || c == '}'), i-pop nako sa stack ang brace.

Ok...so let's further explain how the dot or Dot Notation (.) works.

Whenever you use the Dot Notation, you have to think about two things.
The object before the Dot and the method or property after the Dot.

In java, whenever you access a method or property via dot notation, you can use it as an object right away.

Let's start with stack.peek()

If you look at the documentation for Stack it has a method called peek and it returns an Object.
Stack (Java 2 Platform SE v1.4.2)
That means, aside from an initial reference to a stack when using peek you gain reference to an Object.

(Stack) (Object)
stack . peek()

Since you now have reference to an object with class Object, you can use its methods and properties right away.
Object (Java 2 Platform SE 5.0)
Basing from the documentation, you can find the toString method which returns an object with class String.

(Stack) (Object) (String)
stack. peek(). toString().

Finally, since you now have a reference to a String object, upon looking at its documentation, you can use chatAt(int index) right away.
String (Java 2 Platform SE v1.4.2)

(Stack) (Object) (String) (Character)
stack. peek(). toString(). charAt(index)

So, in summary, the dot notation allows you to gain access of the object before the dot and use its corresponding methods, fields and other properties.

nice pa ka explain in Klave....

nice ka bro..!

@jairoh, hinay-hinayi na jud og sabut ang API sa Java.. hehehe.. sauna ra ko gasulti nga naa ra na sa API, especially sa mga di nimo ma-sabtan..

[crazy_monkey]

good one! nya nasolve nani TS? hehehe

[jairoh_]

solved nani! hahaha. nahan lng tawn ko makasabot. di man sad ni activity namo. practice2x lng kunohay ba

[SuperStar]

na solve na hagbay ra...hehehe
crazy_monkey ang banggiitan nga programmer sa Special Team

good one! nya nasolve nani TS? hehehe

[silent-kill]

kanang toString().charAt(0) gi kuha ra niya ang first character sa string

sample:

ABCDEFG

ang charAt(0) is 'A'

[darkhero]

additional tip about ani nga code:

size = input.length();
for(int x = 0; x < size; x++)

kung di na gamiton ang variable nga size outside sa for loop, do it this way instead:

for(int x = 0, size = input.length(); x < size; x++)

i've been using this ever since nakat-on kog c/c++, applicable gihapon na basta c-like ang programming language nga gigamit such as java. ang advantage kay di na mo-exist outside sa for loop ang variable nga size. this way pwede mka-initiliaze ug daghan nga variable nga sa for loop ra gamiton plus di na mo-conflict outside sa loop.

[street_of_no_return]

    public boolean isParenthesis(char c)
    {
        return c == '(' || c == ')';
    }

is equivalent to

    public boolean isParenthesis(char c)
    {
              if (c == '(' || c == ')')
        return true;
              else
                return false;
    }

tan-awa ari bro kay naa diri ang nindot nga sample ug simple pag ka explain
The ? : operator in Java
hope this helps

superstar ask lang ko ba, diba ang boolean kai true or false raman iya pwde e.return.? pwde d.i nang ina.ana.?

thanks
