String valueOf()

by

This method is used to converts different types of values into a string. You can convert different type of data value into String data value.

You can convert different types:  

  • int to string
  • convert long to string
  • convert boolean to string
  • convert character to string
  • convert float to string
  • convert double to string
  • convert char array to string.

Its return type is String. It is the overload method in the String class. It can accept different type of values.

String.valueOf(DataType value);
class ExampleValueOf
{  
  public static void main(String args[])
  {  
	int intValue = 1;
	float floatValue = 1.1f;
	double doubleValue = 1.2;
	char charValue = 'a';
	char charArray[] = {'J','A','V', 'A'};
	boolean booleanValue = true;
       System.out.println("Converting int to String = "+ String.valueOf(intValue));
       System.out.println("Converting float to String = "+ String.valueOf(floatValue));
       System.out.println("Converting double to String = "+ String.valueOf(doubleValue));
       System.out.println("Converting char to String = "+ String.valueOf(charValue));
       System.out.println("Converting char Array to String = "+ String.valueOf(charArray));
       System.out.println("Converting boolean  to String = "+ String.valueOf(booleanValue));
   }  
}

Output:
Converting int to String = 1
Converting float to String = 1.1
Converting double to String = 1.2
Converting char to String = a
Converting char Array to String = JAVA
Converting boolean  to String = true
