Java - Long toHexString() method
Description
The Java Long toHexString() method returns a string representation of the long argument as an unsigned long in base 16.
Declaration
Following is the declaration for java.lang.Long.toHexString() method
public static String toHexString(long i)
Parameters
i − This is an long to be converted to a string.
Return Value
This method returns the string representation of the unsigned long value represented by the argument in hexadecimal (base 16).
Exception
NA
Example 1
The following example shows the usage of Long toHexString() method to get the hexadecimal string representation of the specified long value. We've created a long variable and assigned it a positive long value. Then using toHexString() method, we're printing the result.
package com.tutorialspoint; public class LongDemo { public static void main(String[] args) { long i = 170L; System.out.println("Number = " + i); /* returns the hexadecimal string representation of the given number */ System.out.println("toHexString = " + Long.toHexString(i)); } }
Output
Let us compile and run the above program, this will produce the following result −
Number = 170 toHexString = aa
Example 2
The following example shows the usage of Long toHexString() method to get the hexadecimal string representation of the specified long value. We've created a long variable and assigned it a negative long value. Then using toHexString() method, we're printing the result.
package com.tutorialspoint; public class LongDemo { public static void main(String[] args) { long i = -170L; System.out.println("Number = " + i); /* returns the hexadecimal string representation of the given number */ System.out.println("toHexString = " + Long.toHexString(i)); } }
Output
Let us compile and run the above program, this will produce the following result −
Number = -170 toHexString = ffffff56
Example 3
The following example shows the usage of Long toHexString() method to get the hexadecimal string representation of the specified long value. We've created a long variable and assigned it a zero value. Then using toHexString() method, we're printing the result.
package com.tutorialspoint; public class LongDemo { public static void main(String[] args) { long i = 0L; System.out.println("Number = " + i); /* returns the hexadecimal string representation of the given number */ System.out.println("toHexString = " + Long.toHexString(i)); } }
Output
Let us compile and run the above program, this will produce the following result −
Number = 0 toHexString = 0
