方法1:采用String的split，驗證代碼如下:
import?java.util.Arrays;
public?class?TestSplit?{
?public?static?void?main(String[]?args)?{
??String?orignString?=?new?String("5,8,7,4,3,9,1");
??String[]?testString?=?orignString.split(",");
??int[]?test?=?{?0,?0,?0,?0,?0,?0,?0?};
??//String?to?int
??for?(int?i?=?0;?i?<?testString.length;?i++)?{
???test[i]?=?Integer.parseInt(testString[i]);
??}
??//sort
??Arrays.sort(test);
??//asc?sort
??for?(int?j?=?0;?j?<?test.length;?j++)?{
???System.out.println(test[j]);
??}
??System.out.println("next?");
//??desc
?????for?(int?i?=?(test.length?-?1);?i?>=?0;?i--)?{
??????System.out.println(test[i]);
?????}
?}
}
方法2:采用StringTokenizer
import?java.util.Arrays;
import?java.util.StringTokenizer;
public?class?SplitStringTest?{
?public?static?void?main(String[]?args)?{
??String?s?=?new?String("5,8,7,4,3,9,1");??
??int?length?=?s.length();
??//split???s?with?","
??StringTokenizer?commaToker?=?new?StringTokenizer(s,?",");
??String[]?result?=?new?String[commaToker.countTokens()];
??int?k?=?0;
??while?(commaToker.hasMoreTokens())?{
???result[k]?=?commaToker.nextToken();
???k++;
??}
??int[]?a?=?new?int[result.length];
??for?(int?i?=?0;?i?<?result.length;?i++)?{
???a[i]?=?Integer.parseInt(result[i]);
??}
??//sort
??Arrays.sort(a);
??//asc?sort
??for?(int?j?=?0;?j?<?result.length;?j++)?{
???System.out.println(a[j]);
??}
?}
}
