integertest.java

基础性的JAVA源代码

package exec.day0928;

public class IntegerTest {
	public static void main(String args[]){
		int a = Integer.parseInt(args[0]);
		int b = Integer.parseInt(args[1]);
		if(a<0 || b<2 || b>36){
			System.out.println("参数不合法！");
			return;
		}
		String str = "0123456789abcdefghijklmnopqrstuvwxyz";
		String s = "";
		for(int i=0;i<a;i++){
			int num = (int)(Math.random()*b);
			char c = str.charAt(num);
//			System.out.println(c);
//			s.concat(c+"");
			s = s+c;
		}
		System.out.println("a : "+a);
		System.out.println("b : "+b);
		System.out.println("获取的字符串 : "+s);
		int n = Integer.parseInt(s,b);
		System.out.println("10进制： "+n);
