How to use string.valueOf() in Java?
In Java, the method String.valueOf() can be used to convert data of other types into a string.
The usage instructions are as follows:
- Utilize primitive data types:
int num = 10;
String strNum = String.valueOf(num);
- Target audience:
Integer num = 10;
String strNum = String.valueOf(num);
- Utilize a character array:
char[] chars = {'a', 'b', 'c'};
String strChars = String.valueOf(chars);
It is important to note that the String.valueOf() method automatically handles null values by converting them to the string “null”.
In addition, the String.valueOf() method also has an overloaded method that can accept a char type parameter and convert it to a string.
char c = 'a';
String strChar = String.valueOf(c);
