Example 1: Java Program to Convert string to int using parseInt() class Main { public static void main(String[] args) { // create string variables String str1 = "23"; String str2 = "4566"; // convert string to int // using parseInt() int num1 = Integer.parseInt(str1); int ...
TheInteger.parseInt()method is used to convert a string to an integer in Java, with the syntaxint num = Integer.parseInt(str);. This function takes a string of digits and transforms it into a usable integer. Here’s a simple example: String str = "123"; int num = Integer.parseInt(st...
Convert a string into an integer in Java usingInteger.parseInt() Now luckily for us, there is a method calledInteger.parseInt(), which makes our life much easier. Let’s say, that we want to convert ourdatavariable into an integer. we can just make a new variable with the namenumber, ...
*/ public class ValueOfDemo { public static void main(String[] args) { // this program requires two // arguments on the command line if (args.length == 2) { // convert strings to numbers float a = (Float.valueOf(args[0])).floatValue(); float b = (Float.valueOf(args[1]))....
@Test public void givenBinaryString_whenParsingInt_shouldConvertToInt() { String givenString = "101010"; int result = Integer.parseInt(givenString, 2); assertThat(result).isEqualTo(42); } Naturally, it’s also possible to use this method with any other radix such as 16 (hexadecimal) or ...
