Java十进制到八进制的转换：Integer.toOctalString()Integer.toOctalString()方法将十进制转换为八进制字符串。 toOctalString()方法的签名如下：
public static String toOctalString(int decimal)让我们看一下在Java中将十进制转换为八进制的简单示例。
//Java Program to demonstrate the use of Integer.toOctalString() method
public class DecimalToOctalExample1{
public static void main(String args[]){
//Using the predefined Integer.toOctalString() method
//to convert decimal value into octal
System.out.println(Integer.toOctalString(8));
System.out.println(Integer.toOctalString(19));
System.out.println(Integer.toOctalString(81));
}}立即测试
输出：
10
23
121Java十进制到八进制的转换：自定义逻辑我们可以使用自定义逻辑在Java中将十进制转换为八进制。
//Java Program to demonstrate the decimal to octal conversion
//using custom code
public class DecimalToOctalExample2{
//creating method for conversion so that we can use it many times
public static String toOctal(int decimal){
int rem;
//declaring variable to store remainder
String octal="";
//declareing variable to store octal
//declaring array of octal numbers
char octalchars[]={'0', '1', '2', '3', '4', '5', '6', '7'};
//writing logic of decimal to octal conversion
while(decimal>
0)
{
rem=decimal%8;
octal=octalchars[rem]+octal;
decimal=decimal/8;
}
return octal;
}
public static void main(String args[]){
//Calling custom method to get the octal number of given decimal value
System.out.println("Decimal to octal of 8 is: "+toOctal(8));
System.out.println("Decimal to octal of 19 is: "+toOctal(19));
System.out.println("Decimal to octal of 81 is: "+toOctal(81));
}}立即测试
【Java将十进制转换为八进制】输出：
Decimal to octal of 8 is: 10
Decimal to octal of 19 is: 23
Decimal to octal of 81 is: 121参考文献
