tooctalstring

整數類toOctalString()方法 (Integer class toOctalString() method)

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

  toOctalString()方法在java.lang包中可用。

• toOctalString() method is used to represent an octal string of the given parameter [value] of integer type as an unsigned integer in base 8.

  toOctalString()方法用于將整數類型的給定參數[value]的八進制字符串表示為以8為底的無符號整數。

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

  toOctalString()方法是一個靜態方法，也可以使用類名進行訪問，如果我們嘗試使用類對象訪問該方法，那么也不會出錯。

• toOctalString() method does not throw an exception at the time of conversion from integer to an octal string.

  從整數轉換為八進制字符串時， toOctalString()方法不會引發異常。

Syntax:

句法：

    public static String toOctalString (int value);

Parameter(s):

參數：

• int value – represents the integer value to be converted.

  int value –表示要轉換的整數值。

Return value:

返回值：

The return type of this method is int, it returns the octal string of the given parameter that represent the unsigned integer value.

此方法的返回類型為int ，它返回給定參數的八進制字符串，該字符串表示無符號整數值。

Example:

例：

// Java program to demonstrate the example 
// of toOctalString (int value) method of Integer class
public class ToOctalStringOfIntegerClass {
public static void main(String[] args) {
// Variables initialization
int i1 = 10;
int i2 = 20;
int i3 = 30;
int i4 = Integer.MAX_VALUE;
int i5 = Integer.MIN_VALUE;
// Integer instance creation
Integer value = new Integer(i1);
// It represents Octal string of the given
// integer type i2 argument
String s = value.toOctalString(i2);
// Display Octal String Representation
System.out.println("value.toOctalString(i2): " + s);
// It represents Octal string of the given
// integer type i3 argument
s = value.toOctalString(i3);
// Display Octal String Representation
System.out.println("value.toOctalString(i3): " + s);
// It represents Octal string of the given
// integer type i4 argument
s = value.toOctalString(i4);
// Display Octal String Representation
System.out.println("value.toOctalString(i4): " + s);
// It represents Octal string of the given
// integer type i5 argument
s = value.toOctalString(i5);
// Display Octal String Representation
System.out.println("value.toOctalString(i5): " + s);
}
}

Output

輸出量

value.toOctalString(i2): 24
value.toOctalString(i3): 36
value.toOctalString(i4): 17777777777
value.toOctalString(i5): 20000000000
