Result is not an integer.Converts a specified value to an equivalent Boolean value.

upto s parseInt('geeksforgeeks', 29) throws a NumberFormatException as the Number system with base 29 can have digits 0-9įollowed by characters a,b,c. ParseInt('2147483648', 10) throws a NumberFormatException parseInt('99', 8) throws a NumberFormatExceptionĪs 9 is not an accepted digit of octal number system parseInt('geeks', 28) throws a NumberFormatException parseInt('geeks', 29) returns 11670324, So, in the cases where leading zeroes are important(in binary representations) avoid using the parseInt() method. String str=”0111” įor the above code, the snippet output is 111.

Convert string to int in java plus#

Any character of the string is not a digit of the specified radix, except that the first character may be a minus sign ‘-‘ (‘-’) or plus sign ‘+’ (‘+’) provided that the string is longer than length 1.The second argument radix is either smaller than Character.MIN_RADIX or larger than Character.MAX_RADIX.Specifically for the parseInt(String s, int radix) variant of the function:.The value represented by the string is not a value of type int.Remember certain key points associated with both the variants: Note: If your String has leading zeroes, the parseInt() method will ignore them.Įxception Thrown: NumberFormatException is thrown by this method if any of the following situations occur. The first method can be considered as an equivalent of the second method with radix = 10 (Decimal). The only difference being is that of the parameter radix. Return Type: Both methods convert the string into its integer equivalent. Note: This parameter is only specific to the second variant of the method. The radix is used while the string is being parsed.It can also have the first character as a minus sign ‘-‘ (‘-’) or plus sign ‘+’ (‘+’) to represent the sign of the number. A string that needs to be converted to an integer.Syntax: public static int parseInt(String s) throws NumberFormatException public static int parseInt(String s, int radix) throws NumberFormatException parseInt(String s, int radix): This function parses the string argument as a signed integer in the radix specified by the second argument.parseInt(String s): This function parses the string argument as a signed decimal integer.Split() String method in Java with examples.Difference between Abstract Class and Interface in Java.
