public class ArrayTest3 {
public static void main(String[] args){
System.out.println(toHex(60));
}

    //将十进制转为16进制
public static String toHex(int num){
char[] chs = new char[8];//定义容器,存储的是字符,长度为8.一个整数最多8个16进制数
int index = chs.length-1;
for(int i = 0;i<8;i++) {
int temp = num & 15; if(temp > 9){
chs[index] = ((char)(temp-10+'A'));
}else {
chs[index] = ((char)(temp+'0'));
} index--;
num = num >>> 4;
}
return toString(chs);
}
//将数组转为字符串
public static String toString(char[] arr){
String temp = "";
for(int i = 0;i<arr.length;i++){
temp = temp + arr[i];
}
return temp;
}
}
