Hi,

In Java you can convert String to in with the help of following two functions:

  • Integer.parseInt()

  • Integer.valueOf()

Both these functions takes String variable and converts into int. If there is conversion error then it displays following error: * java.lang.NumberFormatException

You should put your conversion code within try{} cartch{} block.

Here is example code:

package net.roseindia;

public class StringToInt {

    public static void main(String[] args) {
        try{
            String strValue = "105";

            int converted = Integer.parseInt(strValue);
            System.out.println("Converted value:"+converted);

            converted = Integer.valueOf(strValue);
            System.out.println("Converted value:"+converted);
        }catch(Exception e){
            System.out.println(e.getMessage());
        }

    }

}

Thanks
