Elements can be filled in a float array using the java.util.Arrays.fill() method. This method assigns the required float value to the float array in Java. The two parameters required are the array name and the value that is to be stored in the array elements.A program that demonstrates this is given as follows −Example Live Demoimport java.util.Arrays; public class Demo { public static void main(String[] argv) throws Exception { float[] floatArray = new float[5]; float floatValue = 8.5F; Arrays.fill(floatArray, floatValue); System.out.println("The float array content is: " + Arrays.toString(floatArray)); ...

To format message with medium style format of date in Java, we use the MessageFormat class and the Date class. The MessageFormat class gives us a way to produce concatenated messages which are not dependent on the language. The MessageFormat class extends the Serializable and Cloneable interfaces.Declaration − The java.text.MessageFormat class is declared as follows −public class MessageFormat extends FormatThe MessageFormat.format(pattern, params) method formats the message and fills in the missing parts using the objects in the params array matching up the argument numbers and the array indices.The format method has two arguments, a pattern and an array of arguments. ...

Binary search on a char array can be implemented by using the method java.util.Arrays.binarySearch(). This method returns the index of the required char element if it is available in the array, otherwise, it returns (-(insertion point) - 1) where the insertion point is the position at which the element would be inserted into the array.A program that demonstrates this is given as follows −Example Live Demoimport java.util.Arrays; public class Demo { public static void main(String[] args) { char c_arr[] = { 'b', 's', 'l', 'e', 'm' }; Arrays.sort(c_arr); System.out.print("The sorted array ...
