Java进制转换
## 代码
```java
public static void main(String[] args) {
int number = 10;
System.out.println("转为二进制：");
System.out.println(Integer.toString(number, 2));
System.out.println(Integer.toBinaryString(number));
System.out.println("\n转为八进制：");
System.out.println(Integer.toString(number, 8));
System.out.println(Integer.toOctalString(number));
System.out.println("\n转为十六进制：");
System.out.println(Integer.toString(number, 16));
System.out.println(Integer.toHexString(number));
System.out.println("\n八进制声明(012)：");
System.out.println(012);
System.out.println("\n十六进制声明(0xa)：");
System.out.println(0xa);
}
```
