Java数组排序：选择排序法

import java.util.Arrays;
public class JavaTest {
public static void main (String args[]){

int a[] = {12,45,67,89,123,-45,67};
System.out.println(Arrays.toString(a));
int N = a.length;
for(int i=0; i) {
for(int j=i+1;j){
if(a[j]<a[i]){
int t = a[j];
a[j] = a[i];
a[i] = t;
}

}

}
System.out.println(Arrays.toString(a));
}

}
