This method is used to get the primitive data type of a certain String. parseXxx() is a static method and can have one argument or two.

Syntax:

All the variant of this method are given below:

static int parseInt(String s)
static int parseInt(String s, int radix)

Parameters:

Here is the detail of parameters:

s -- This is a string representation of decimal.

radix -- This would be used to convert String s into integer.

Return Value:

parseInt(String s): This returns an integer (decimal only).

parseInt(int i): This returns an integer, given a string representation of decimal, binary, octal, or hexadecimal (radix equals 10, 2, 8, or 16 respectively) numbers as input.

Example:

public class Test{

   public static void main(String args[]){

      int x =Integer.parseInt("9");

      double c = Double.parseDouble("5");

      int b = Integer.parseInt("444",16);

      System.out.println(x);

      System.out.println(c);

      System.out.println(b);

   }

}

This produces the following result:
