Java - Convert integer to string

To convert an integer to a string in Java, you can use one of the following methods:

  1. Using Integer.toString() or String.valueOf():

    You can use the Integer.toString() method or String.valueOf() method to convert an integer to its string representation:

    int number = 42; // Using Integer.toString() String str1 = Integer.toString(number); // Using String.valueOf() String str2 = String.valueOf(number); System.out.println("String 1: " + str1); System.out.println("String 2: " + str2);

  2. Using String Concatenation:

    You can also convert an integer to a string by concatenating it with an empty string:

    int number = 42; String str = "" + number;

  3. Using String.format():

    You can use the String.format() method to format the integer as a string:

    int number = 42; String str = String.format("%d", number);

  4. Using StringBuilder or StringBuffer:

    You can use StringBuilder or StringBuffer to append the integer to a string:

    int number = 42; StringBuilder stringBuilder = new StringBuilder(); stringBuilder.append(number); String str = stringBuilder.toString();

All of these methods will convert the integer 42 to the string "42". You can choose the one that fits your coding style and requirements.
