The way I know how to convert an integer into a string is by using the following code: Integer.toString(int); and. String.valueOf(int); If you had an integer i, and a string s, then the following would apply: int i; String s = Integer.toString(i); or. String s = String.valueOf(i);
The two main ways to do this are using the method valueOf() and method parseInt() of the Integer class. Suppose you are given a String like this. String numberInString = "999"; Then you can convert it into integer by using. int numberInInteger = Integer.parseInt(numberInString); And alternatively, you can use.
Nov 5, 2010 · If you say String.valueOf (i), Java converts the integer to a string and returns the result. If you say ""+i, Java creates a StringBuilder object, appends an empty string to it, converts the integer to a string, appends this to the StringBuilder, then converts the StringBuilder to a String. That's a lot of extra steps.
Mar 9, 2010 · 4. if the int value is 15, you can convert it to a binary as follows. int x = 15; Integer.toBinaryString(x); if you have the binary value, you can convert it into int value as follows. String binaryValue = "1010"; Integer.parseInt(binaryValue, 2); answered Oct 22, 2021 at 13:56.
In this case you could also do : String str = "" + i; Similarly, one of the easiest way to convert primitive datatypes to String is to use the toString() method with the datatype object of the element to be converted. String str = Double.toString(d); // Convert double to String. String str = Long.toString(l); //Convert long to String.
6. There are many ways to convert an int to ASCII (depending on your needs) but here is a way to convert each integer byte to an ASCII character: private static String toASCII(int value) {. int length = 4; StringBuilder builder = new StringBuilder(length); for (int i = length - 1; i >= 0; i--) {. builder.append((char) ((value >> (8 * i)) & 0xFF));
Jan 30, 2011 · String s = String.valueOf(i); String s = Integer.toString(i); Another more concise way is: String s = "" + i; See it working online: ideone. This is particularly useful if the reason you are converting the integer to a string is in order to concatenate it to another string, as it means you can omit the explicit conversion:
Mar 27, 2013 · Mar 27, 2013 at 20:59. 1. The fastest way to convert an integer to a string is probably to use Integer.toString (int). (Though a clever programmer could probably do considerably better.) – Hot Licks. Mar 27, 2013 at 21:09.
May 31, 2017 · Which means that if you use the radix 10, you better call the Integer.toString (int foo) directly. For the other cases use the Integer.toString (int foo, int radix). The concat solution first transforms the int value into a String and later concatenates with the empty String. This obviously is the most expensive case.
Jun 6, 2012 · public static String toString(int[] a) Returns a string representation of the contents of the specified array. The string representation consists of a list of the array's elements, enclosed in square brackets ("[]"). Adjacent elements are separated by the characters ", "(a comma followed by a space). Elements are converted to strings as by ...
