  1. Integer.parseInt() Examples. Example to convert aString“10” to an primitive int.
  2. Integer.valueOf() Examples. Alternatively, you canuseInteger.valueOf() , it will returns an Integer object.
  3. NumberFormatException.

Likewise, can you convert string to int python? Converting Strings to Numbers Strings can be converted to numbers by usingtheint() and float() methods. If your stringdoesnot have decimal places, you'll most likely wanttoconvert it to an integer by using theint()method.
