convert to integer?

[Cedric Moonen]

Of course you can't cast a String to an Integer, they are two completely unrelated types. You have to use the Integer.valueOff(String s) method:

Integer addIncidentID = Integer.valueOff(getIncidentidtxt().getValue());

this is a static method of the type Integer:

int iValue = Integer.parseInt(givenString);

This one throws an exception when converting fails. So best is to wrap in a try/catch:

int iValue=0; // declared and initialized to a simple value (could be -1 when 0 is used)
try{
iValue = Integer.parseInt(givenString);
}
catch(NumberFormatException oException){
// doShowFunnyPopup();
}

can i use interger.parseint?

[TorstenH]

that's kind of the one I mentioned - if "interger" is just a typo and is supposed to be "Integer". see post above your post. regards Torsten

Please, check the javadoc ! Yes you can use parseInt but it returns an int, not an Integer. So, depending on your needs, either use valueOf or parseInt.

how do i convert from string to integer?

you can convert string to integer by using various ways you can use valueOf method of Integer class in this way

Integer obj = Integer.valueOf(str_value); // str_value is your string value

you can use Integer Constructor

Integer obj = new Integer(str_value);

you can use parseInt method

int objt = Integer.parseInt(str_value);

For Example: String abc123 = "123"; Integer abcint = Integer.valueOf(abc123);

// to primitive int i from Integer Object ii int i = ii.intValue(); // to Integer ii from primitive int i Integer ii = new Integer( i );

int int_page_id=o; String str_page_id="5"; try { int_page_id = Integer.parseInt(str_page_id); } catch(NumberFormatException ex) { ex.printStackTrace(); }

String a="2"; int value = Integer.parseInt(a);
