tohexstring方法

長類toHexString()方法 (Long class toHexString() method)

• toHexString() method is available in java.lang package.

  toHexString()方法在java.lang包中可用。

• toHexString() method is used to represent a hexadecimal string of the given parameter [value] of long type as an unsigned long in base 16.

  toHexString()方法用于將long類型給定參數[value]的十六進制字符串表示為以16為基數的無符號long。

• toHexString() method is a static method, it is accessible with the class name too and if we try to access the method with the class object then also we will not get an error.

  toHexString()方法是一個靜態方法，也可以使用類名進行訪問，并且如果我們嘗試使用類對象訪問該方法，那么我們也不會收到錯誤。

• toHexString() method does not throw an exception at the time of conversion from long integer to Hexadecimal string.

  從長整數轉換為十六進制字符串時， toHexString()方法不會引發異常。

Syntax:

句法：

public static String toHexString (long value);

Parameter(s):

參數：

• long value – represents the long value to be converted.

  long value –表示要轉換的long值。

Return value:

返回值：

The return type of this method is String, it returns the hexadecimal string of the given parameter that represent the unsigned long value.

此方法的返回類型為String ，它返回給定參數的十六進制字符串，該字符串表示無符號long值。

Example:

例：

// Java program to demonstrate the example // of toHexString (long value) method of Long classpublic class ToHexStringOfLongClass {public static void main(String[] args) {// Variables initializationlong l1 = 10;long l2 = 20;long l3 = 30;long l4 = Long.MAX_VALUE;long l5 = Long.MIN_VALUE;// Long instance creationLong value = new Long(l1);// It represents hexadecimal string of the given// long type l2 argumentString s = value.toHexString(l2);// Display Hexadecimal String RepresentationSystem.out.println("value.toHexString(l2): " + s);// It represents hexadecimal string of the given// long type l3 arguments = value.toHexString(l3);// Display Hexadecimal String RepresentationSystem.out.println("value.toHexString(l3): " + s);// It represents hexadecimal string of the given// long type l4 arguments = value.toHexString(l4);// Display Hexadecimal String RepresentationSystem.out.println("value.toHexString(l4): " + s);// It represents hexadecimal string of the given// long type l5 arguments = value.toHexString(l5);// Display Hexadecimal String RepresentationSystem.out.println("value.toHexString(l5): " + s);} }

Output

輸出量

value.toHexString(l2): 14 value.toHexString(l3): 1e value.toHexString(l4): 7fffffffffffffff value.toHexString(l5): 8000000000000000
