toString
public String toString()
Returns a String object representing this Integer's value. The value is converted to signed decimal representation and returned as a string, exactly as if the integer value were given as an argument to the toString(int) method.

Overrides:
toString in class Object
Returns:
a string representation of the value of this object in base 10.

or can try


Integer.parseInt(x) converts String to int.

>> convert a string to a integer

String s = Integer.toString(i)  ??? Perhaps typed that a little too fast ;-) ?

Anyway, you can also use: int i = new Integer ( stringObject ).intValue (). However, it might be better to use Integer.parseInt ( stringObject ) as it is useless to instantiate an extra object.

U can use the following example...

String str = "10";
int strValue = Integer.parseInt(str).intValue();

which would give the value 10 into the variable strValue.

>> int strValue = Integer.parseInt(str).intValue();

No. Integer.parseInt () is enough. You cannot do an intValue () over a result from parseInt () because parseInt () returns a simple 'int and not an Integer object. Or else you can do: new Integer ( str ).intValue () -> but like I said, its a useless instantiation of an extra object.

Felipe1976,

We still don't know if you were trying to convert a String to an integer or an integer to a String?
