In Java, converting a String to an int is a common requirement when working with user input, data parsing, or file handling. For instance, when you receive numerical data as a String (e.g., from a text field in a form or a configuration file), you need to convert it to an int fo...
One way is touse theBigInteger(String value, int radix)constructor: StringinputString="290f98";BigIntegerresult=newBigInteger(inputString,16); assertEquals("2690968", result.toString());Copy In this case, we’re specifying theradix,or base, as 16 for converting hexadecimal to decimal. The othe...
Converting a String Into an int Using atoi Before I leave the string section, I'd like to talk about two useful functions that could come in handy later on. Both of these require the stdlib.h First of all, atoi. This converts strings, like "23" or even "29dhjds" into integers (re...
Java int to String with Integer.toString Integer.toStringconverts its argument to signed decimal representation and returned as a string. Main.java void main() { int numOfApples = 16; String msg = "There are " + Integer.toString(numOfApples) + " apples"; ...

String name = jsonObject.getString("name"); int age = jsonObject.getInt("age"); String city = jsonObject.getString("city"); // Create Java object Person person = new Person(name, age, city); // Output System.out.println(person); ...
System.out.println(StringUtils.join(intList,"|")); } Output: 1|2|3 Again, this implementation is internally dependent on thetoString()implementation of the type we're considering. 5. Conclusion In this article, we learned how easy it is to convert aListto aStringusing different techniques....
public class ToStringDemo { public static void main(String[] args) { double d = 858.48; String s = Double.toString(d); int dot = s.indexOf('.'); System.out.println(dot + " digits " + "before decimal point."); System.out.println( (s.length() - dot - 1) + " digits after...
String inputString = "290f98"; new BigInteger(inputString); This exception can be handled in two ways. One way is to use the BigInteger(String value, int radix) constructor: String inputString = "290f98"; BigInteger result = new BigInteger(inputString, 16); assertEquals("2690968", result...
