Java String valueOf() method explained with examples

Java String valueOf() method returns the String representation of the boolean, char, char array, int, long, float and double arguments. We have different versions of this method for each type of arguments. The signature of this method is as follows:

Method valueOf() signature:

public static String valueOf(boolean b): Used for converting boolean value to a String
public static String valueOf(char c): char to String
public static String valueOf(int i): int to String
public static String valueOf(long l): long to String
public static String valueOf(float f): float to String
public static String valueOf(double d): double to String

Java String valueOf() Example

In example we are using Java String valueOf() method to convert the integer, float, long, double, char and char array to the String.

public class Example{  
   public static void main(String args[]){  
	int i = 10; //int value
	float f = 10.10f; //float value
	long l = 111L; //long value
	double d = 2222.22; //double value
	char ch = 'A'; //char value
	char array[] = {'a', 'b', 'c'}; //char array
		
	//converting int to String
	String str1 = String.valueOf(i); 
		
	//converting float to String
	String str2 = String.valueOf(f); 
		
	//converting long to String
	String str3 = String.valueOf(l);
		
	//converting double to String
	String str4 = String.valueOf(d);
		
	//converting char to String
	String str5 = String.valueOf(ch);
		
	//converting char array to String
	String str6 = String.valueOf(array);
	System.out.println(str1);
	System.out.println(str2);
	System.out.println(str3);
	System.out.println(str4);
	System.out.println(str5);
	System.out.println(str6);
   }
}

Output:

10
10.1
111
2222.22
A
abc
