Here are four different ways you can use to convert an int to String in Java. Most of them are very similar to what we have used to convert an Integer to a String because you can easily convert an int to Integer using Autoboxing. Some method reuses each other like valueOf(), which i...

Long.valueOf(hex, radix); Long.decode(hex); new BigInteger(hex, radix); The following exampleconverts a hexadecimal toIntegertype using the defined methods. The same can be done forhexadecimal to Long conversion. Stringhex="10D";intdecimal=Integer.parseInt(hex,16);//orintdecimal=Integer.valu...
toconvert String to int in Java, first, by using the constructor ofIntegerclass, second, by usingparseInt()method ofjava.lang.Integer,and third, by usingInteger.valueOf()method. Though all those methods return an instance ofjava.lang.Integer, which is a wrapper class for primitive int value...
@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 ...
