tohexstring方法

长类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()方法用于将long类型给定参数[value]的十六进制字符串表示为以16为基数的无符号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()方法是一个静态方法，也可以使用类名进行访问，并且如果我们尝试使用类对象访问该方法，那么我们也不会收到错误。

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

  从长整数转换为十六进制字符串时， toHexString()方法不会引发异常。

Syntax:

句法：

    public static String toHexString (long value);

Parameter(s):

参数：

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

  long value –表示要转换的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.

此方法的返回类型为String ，它返回给定参数的十六进制字符串，该字符串表示无符号long值。

Example:

例：

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

Output

输出量

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