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