| 10 | +In this article you are going to learn how can you convert an integer to a String. |
| 11 | + |
| 12 | +There are multiple ways we can convert an int to string in java. let's check what are they. |
| 13 | + |
| 14 | +1.`String.ValueOf()` method |
| 15 | +2.`Integer.toString()` method |
| 16 | +3. String.format() method |
| 17 | + |
| 18 | +##1.`String.valueOf()` method |
| 19 | + |
| 20 | +`String.valueOf()` method returns the string representation of the`Object` argument. |
| 21 | + |
| 22 | +So when we pass an int as parameter to`valueOf()` method, it returns it's String representation. |
| 23 | + |
| 24 | +If the argument is`null`, then a string equal to`"null"`will be returned. |
| 25 | + |
| 26 | +Internally`valueOf()` method calls`toString()` method on the object argument to get its string representation. |
| 27 | + |
| 28 | +An example to convert an int to string using`valueOf()` method is given below. |
| 29 | + |
| 30 | +```java |
| 31 | +/* |
| 32 | + * A program to convert an int to string in java using |
| 33 | + * the String.toSTring() method. |
| 34 | + * |
| 35 | + * @author Gaurav Kukade at coderolls.com |
| 36 | +*/ |
| 37 | + |
| 38 | +publicclassIntToSTring{ |
| 39 | + |
| 40 | +publicstaticvoidmain(String []args){ |
| 41 | + |
| 42 | +int number=1234; |
| 43 | + |
| 44 | +String numberString=String.valueOf(number); |
| 45 | + |
| 46 | +//print string value of number |
| 47 | +System.out.println("numberString:"+ numberString); |
| 48 | + } |
| 49 | +} |
| 50 | +``` |
| 51 | +Output |
| 52 | +```java |
| 53 | +numberString:1234 |
| 54 | +``` |
| 55 | + |
| 56 | +##2.`Integer.toString()` method |
| 57 | + |
| 58 | +`Integer.toString()` method returns the String object of the Integer's value. |
| 59 | + |
| 60 | +The value is converted to signed decimal representation and returned as a string, exactly as if the integer value were given as an argument to the`toString()` method. |
| 61 | + |
| 62 | +An example to convert an int to string using the`toString()` method is given below. |
| 63 | + |
| 64 | +```java |
| 65 | +/* |
| 66 | + * A program to convert an int to string in java using |
| 67 | + * the Integer.toString() method. |
| 68 | + * |
| 69 | + * @author Gaurav Kukade at coderolls.com |
| 70 | +*/ |
| 71 | + |
| 72 | +publicclassIntToSTring{ |
| 73 | + |
| 74 | +publicstaticvoidmain(String []args){ |
| 75 | + |
| 76 | +int number=1234; |
| 77 | + |
| 78 | +//String numberString = String.valueOf(number); |
| 79 | + |
| 80 | + |
| 81 | +String numberString=Integer.toString(number); |
| 82 | +//print string value of number |
| 83 | +System.out.println("numberString:"+ numberString); |
| 84 | + } |
| 85 | +} |
| 86 | +``` |
| 87 | +Output |
| 88 | +```java |
| 89 | +numberString:1234 |
| 90 | +``` |
