java中实现字符串转换成数组

import java.util.*;

import java.util.regex.*;

class StrToArr

{

public static void main(String[] args)

{

int i=0;

int[] arr={0};

String Str="0100110110";

byte[] buf=Str.getBytes();//转换成byte数组

for(int j=0;j<buf.length;j++)

{

System.out.println(buf[j]);//输出的为0或1的ASCII码

}

String str="25536,12578,2,3,4,5,77777,888,99";

Scanner scanner = new Scanner(str).useDelimiter(",");//以“，”为分隔符，将输入的字符串分割

while(scanner.hasNextInt())

{

arr[i]=scanner.nextInt();//将分割的字符串转换成整型数组

System.out.println(arr[i]);

}

//scanner.close();

}

}
