Let us first declare a Float object.Float ob = new Float("29.35");Now, let us convert it to numeric primitive data type short using shortValue()short val1 = ob.shortValue();In the same way, we can convert it to int using intValue() method.short val1 = ob.intValue();The following is an example that converts Float to other numeric primitive data types as well.Example Live Demopublic class Demo { public static void main(String args[]) { Float ob = new Float("29.35"); // numeric primitive data types short val1 = ob.shortValue(); System.out.println(val1); int val2 = ...

The Float.valueOf() method is used in Java to convert string to float.The following are our string values.String str1 = "100.5"; String str2 = "200.5";To convert the string value to float, try the method valueOf()float val1 = (Float.valueOf(str1)).floatValue(); float val2 = (Float.valueOf(str2)).floatValue();The following is the complete example with output.Example Live Demopublic class Demo { public static void main(String args[]) throws Exception { String str1 = "100.5"; String str2 = "200.5"; float val1 = (Float.valueOf(str1)).floatValue(); float val2 = (Float.valueOf(str2)).floatValue(); System.out.println("Multiplication = " + (val1 * val2)); } }OutputMultiplication = 20150.25

To display the month number, use the SimpleDateFormat(“M”)// displaying month number Format f = new SimpleDateFormat("M"); String strMonth = f.format(new Date()); System.out.println("Month Number = "+strMonth);Since, we have used the Format and SimpleDateFormat class above, therefore import the following packages. With that, we have also used the Date.import java.text.Format; import java.text.SimpleDateFormat; import java.util.Date;Example Live Demoimport java.text.Format; import java.text.SimpleDateFormat; import java.util.Date; import java.util.Calendar; public class Demo { public static void main(String[] args) throws Exception { // displaying current date and time Calendar cal = Calendar.getInstance(); SimpleDateFormat simpleformat = new SimpleDateFormat("dd/MMMM/yyyy hh:mm:s"); ...

In Java, verifying whether a string is a valid number is a common requirement in various applications. This process ensures that the string can be safely converted to a numerical type without causing runtime exceptions. To validate if a string can be converted to these types, we use the Integer.parseInt() and Float.parseFloat() methods, respectively. Problem Statement Given a string that may contain an integer or a float value, write a Java program to check whether it is valid number or not. Input "100" //string value Output 100 // ... Read More

Float is a wrapper class provided to wrap float primitive value.Let us create a Float object with float primitive.// float primitive float myFloat = 24.22f; // Float object Float obj1 = new Float(myFloat);Let us now create a Float object from string.Float obj2 = new Float("39.87");The following is an example that displays both the ways discussed above with output.Example Live Demoimport java.lang.*; public class Demo { public static void main(String args[]) { float myFloat = 24.22f; Float obj1 = new Float(myFloat); System.out.println(obj1); Float obj2 = new Float("39.87"); System.out.println(obj2); } }Output24.22 39.87

The isNan() method returns true if the Float value is a Not-a-Number (NaN). Let’s say we have the following Float values.Float f1 = new Float(5.0/0.0); Float f2 = new Float(10.2/0.0); Float f3 = new Float(0.0/0.0);Check with isNaN() method.f1.isNaN (); f2.isNaN (); f3.isNaN ();The following is the complete example with output.Example Live Demoimport java.lang.*; public class Demo { public static void main(String args[]) { Float f1 = new Float(5.0/0.0); Float f2 = new Float(10.2/0.0); Float f3 = new Float(0.0/0.0); System.out.println(f1.isNaN()); System.out.println(f2.isNaN()); System.out.println(f3.isNaN()); ...
