存储字符串数组分别指定变量

我是JAVA的初学者，我正在编写这个代码，它应该接收一个字符串数组，并将每个字符串（数组元素）分别存储在指定的变量中。 但它只存储第一个元素。 以下是代码：

package ontoretrive; import org.apache.commons.lang3.ArrayUtils; public class j { static String sss= "male,O+,45,saudi,brain_diseases"; static int size =sss.length(); static String male=""; static String blood=""; static String age=""; static String nat=""; static String dis=""; static char temp; static void func (){ char[] charArray = sss.toCharArray(); Character[] charObjectArray = ArrayUtils.toObject(charArray); int count=0; int x=0; while (x< size){ temp =charObjectArray[x]; while(temp!=','&&count==0){ male=male+temp; x++; temp =charObjectArray[x];} x++; temp =charObjectArray[x]; count++; while(temp!=','&&count==1){ blood=blood+temp; x++; temp =charObjectArray[x];} x++; temp =charObjectArray[x]; count++; while(temp!=','&&count==2){ age=age+temp; x++; temp =charObjectArray[x]; }x++; temp =charObjectArray[x]; count++; while(temp!=','&&count==3){ nat=nat+temp; x++; temp =charObjectArray[x]; }x++; temp =charObjectArray[x]; count++; while(temp!=','&&count==4){ dis=dis+temp; x++; //temp =charObjectArray[x]; } x++; // temp =charObjectArray[x]; count++; } System.out.println(male);//end while1 System.out.println(blood);//end while1 System.out.println(age);//end while1 System.out.println(nat);//end while1 System.out.println(dis);//end while1 }//end func public static void main(String[] args) { System.out.println("dis1"); func(); System.out.println(male);//end while1 //System.out.println("dis3"); } } //end class

 public class j { static String sss = "male,O+,45,saudi,brain_diseases"; static int size = sss.length(); //I suggest you not to give them a start value or set them as null static String male = ""; static String blood = ""; static String age = ""; static String nat = ""; static String dis = ""; static void func() { //it uses the "," character to breaks the string sss into pieces //so became into "male","O+","45","saudi","brain_diseases" String[] pieces = sss.split(","); //pieces[0] is the first piece so = "male" //pieces[1] is the second "O+" and so on male = pieces[0]; blood = pieces[1]; age = pieces[2]; nat = pieces[3]; dis = pieces[4]; System.out.println(male); System.out.println(blood); System.out.println(age); System.out.println(nat); System.out.println(dis); } public static void main(String[] args) { func(); } }

使用String的split（）方法可以更轻松地完成您正在尝试的操作：

 static void func (){ String[] split = sss.split(","); if (split.length < 5) { // this means some error in the input, need to handle } male=split[0]; blood=split[1]; age=split[2]; nat=split[3]; dis=split[4]; }
