Getting Double from a double Value Example

The following example shows the usage of Double valueOf() method to get a Double object of a double value. We've initialized one Double object with a positive double using valueOf() method. Then we're printing the string representation value of the object.

package com.tutorialspoint;
public class DoubleDemo {
   public static void main(String[] args) {
      Double d1 = Double.valueOf(6.5);
  
      // print the Double instance representing the specified double value 
      System.out.println("Value = " +  d1);
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value = 6.5

Getting Double from a Negative double Value Example

The following example shows the usage of Double valueOf() method to get a Double object of a double value. We've initialized one Double object with a negative double using valueOf() method. Then we're printing the string representation value of the object.

package com.tutorialspoint;
public class DoubleDemo {
   public static void main(String[] args) {
      Double d1 = Double.valueOf(-6.5);
   
      // print the Double instance representing the specified double value 
      System.out.println("Value = " +  d1);
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value = -6.5

Getting Double from a Negative Zero Example

The following example shows the usage of Double valueOf() method to get a Double object of a double value. We've initialized one Double object with a negative zero double using valueOf() method. Then we're printing the string representation value of the object.

package com.tutorialspoint;
public class DoubleDemo {
   public static void main(String[] args) {
      Double d1 = Double.valueOf(-0.0);
   
      // print the Double instance representing the specified double value 
      System.out.println("Value = " +  d1);
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value = -0.0

Getting Double from a Positive Zero Example

The following example shows the usage of Double valueOf() method to get a Double object of a double value. We've initialized one Double object with a positive zero double using valueOf() method. Then we're printing the string representation value of the object.

package com.tutorialspoint;
public class DoubleDemo {
   public static void main(String[] args) {
      Double d1 = Double.valueOf(0.0);
   
      // print the Double instance representing the specified double value 
      System.out.println("Value = " +  d1);
   }
} 

Output

Let us compile and run the above program, this will produce the following result −

Value = 0.0
