Convert String to Number
In this section, we will learn how to convert String to Number.
The following program provides you the functionality to convert String to Number.
Code Description:
In this program we have taken a String of int, byte,
boolean, double as shown below and also we have used the method MIN
_VALUE and MAX_VALUE of different wrapper classes to print all the values on int,
short, double etc.
Here is the code of the program:
public class StrToNum{
public static void main (String args[]){
String table = "Table of the Java Numbers\n" +
"Primitive Type\tSize in Bits\tTypical Value\tMinimum Value
\tMaximum Value\n" +
"**************\t**************\t**************\t**********
****\t**************\n";
// int
table += "int\t\t" + 32 + "\t\t" + 65536 + "\t\t" + Integer.MIN_VALUE
+ "\t" + Integer.MAX_VALUE + "\n";
// byte
table += "byte\t\t" + 8 + "\t\t" + (byte)5 + "\t\t" + Byte.MIN_VALUE
+ "\t\t" + Byte.MAX_VALUE + "\n";
// short
table += "short\t\t" + 16 + "\t\t" + (short)1024 + "\t\t" + Short.MIN_VALUE
+ "\t\t" + Short.MAX_VALUE + "\n";
//boolean
table += "boolean\t\t" + "\t\t" + true + ',' + false + "\t\t" + "\n";
// double
table += "double\t\t" + 64 + "\t\t" + 100e100 + "\t\t" + Double.MIN_VALUE +
"\t" + Double.MAX_VALUE + "\n";
table +=
"**************\t**************\t**************\t***************\t************\n";
System.out.println(table);
}
}
