numsort.java

这是一系列的java关于数组的程序

public class NumSort {
	public static void main(String[] args) {
		int a[] = new int[args.length];
		for(int i=0; i<a.length; i++) {
			a[i] = Integer.parseInt(args[i]);
		}
		print(a);
		selectionSort(a);
		print(a);
	}
	
	private static void print(int a[]) {
		for(int i=0; i<a.length; i++)
			System.out.print(a[i] + " ");
		System.out.println();
	}
	
	private static void selectionSort(int a[]) {
		int k,temp;
		for(int i=0; i<a.length; i++) {
			k = i;
			for(int j=k+1; j<a.length; j++) {
				if(a[k] > a[j]) {
					k = j;
				}
		 }
		 if (k != i) {
		 	temp = a[i];
		 	a[i] = a[k];
		 	a[k] = temp;
		}
		}
	}
	
}
