  • This program carries out the task of transforming a given string value into its Integer equivalent.
  • For the conversion purpose valueOfmethod of Integer class, is employed.
  • First a String type variables str1 is declared.
  • Then the variable is passed to valueOf() method as argument.
  • The very next step involves the assignment of the resulting value to int type variable num1.
  • Finally, the result is displayed.
  • This method valueOf() differs from parseInt() in a sense that it first converts the values into an integer object then those objects are turned into integer values.
  • This process is termed as ‘unboxing’, specifically in Java.
