字符串转整型数组，并排序输出

public class b1 {

public static void main(String[] args) {
metod2();

}
public static void metod2(){
String a = "1,4,7,13,5,17,9";
String str[] = a.split(",");
int max = 0;
int array[] = new int[str.length];
for(int i=0;i<str.length;i++){
array[i]=Integer.parseInt(str[i]);
}
int k = 0;

for(int m = 0; m<array.length; m++){
for(int j = 0;j<array.length-1;j++){
if(array[j]>array[j+1]){
k=array[j];
array[j]=array[j+1];
array[j+1]=k;
}

}System.out.print(array[m]);
}
}
}
