To compare two Java double arrays, use the Arrays.equals() method. The following are our double arrays.double[] arr1 = new double[] { 1.3, 7.2, 4.2 }; double[] arr2 = new double[] { 1.3, 7.2, 4.2 }; double[] arr3 = new double[] { 2.8, 5.3, 9.8 }; double[] arr4 = new double[] ... Read More

Let us first declare a Double −Double ob = new Double(99.12);Use the toString() method to convert Double into String.String res = ob.toString();The following is the complete example.Example Live Demopublic class Demo {    public static void main(String args[]) {       Double ob = new Double(99.12);       String res = ob.toString();       System.out.println(res); } }Output99.12Read More

To convert a String to a double type number in Java, use the Double.parseDouble() method.Here is our string.String str = "699.7e130";Let us now convert the above string to double.double val = Double.parseDouble(str);Example Live Demopublic class Demo { public static void main(String args[]) { String str = "699.7e130"; ...

To convert String to Double in Java, you can use the following three examples. Two of them are using in-built methods parseDouble() and valueOf(). However, one of the method isn’t using a method.Let us work through them one by one.The following is an example to convert String to Double without ... Read More

Let’s say we have Double object here. Double obj = new Double("39.45"); Now, if we want to convert this Double to short primitive data type. For that, use the in-built shortValue() method. // converting to short primitive types short shortObj = obj.shortValue(); System.out.println(shortObj); In the same ... Read More

The java.lang.Math class contains methods for performing basic numeric operations such as the trigonometry, logarithm, etc. The following are some of the methods. Sr.No Methods & Description 1 static double abs(double a) This method returns the absolute value of a double value. 2 static ... Read More

Let’s say we have the following three values − double val1 = 15.546; double val2 = 25.87; double val3 = Math.PI; Let us now format these double-type numbers. Firstly, we are formatting Euler’s number with Math.exp(). After that, we have also evaluated log. The %.3f you can see ... Read More

To compare Double in Java, use the following methods − Method 1: compareTo() method in Java The java.lang.Double.compareTo() method compares two Double objects. Example Live Demo import java.lang.*; public class Demo { public static void main(String args[]) { Double ... Read More

To convert double value to string, use the toString() method in Java. The method represents a value in string. Let’s say the following is our double to be converted. double doubleVal = 333.24; Now, convert it to string. String str = Double.toString(doubleVal); The following is the ... Read More

The java.lang.Double.isNan() method returns true if the specified number is a Not-a-Number (NaN) value, false otherwise. Let’s say the following are our Double values. Double val1 = new Double(3/0.); Double val2 = new Double(0/0.); Now, we will use the isNan() method to check whether the number is a ... Read More

The Double isInfinite() method returns true if this Double value is infinitely large in magnitude, false otherwise. Let’s say we have the following Double values. Double val1 = new Double(3/0.); Double val2 = new Double(0/0.); Use the isInfinite() method now. The return value is a boolean. val1.isInfinite(); ... Read More

To convert double primitive type to a Double object, you need to use Double constructor. Let’s say the following is our double primitive. // double primitive double val = 23.78; To convert it to a Double object, use Double constructor. // Double object Double ob = new ... Read More

Let’s say we have the following two values. double val1 = 20.932; double val2 = 11.67; Let us now format these floating-point numbers. Firstly, we are formatting euler’s number withMath.exp(). After that, we have also evaluated log. The %.3f you can see here is what we used for ... Read More
