java中if与switch-case语句的使用及一些注意事项

1.if语句的嵌套

import java.util.Scanner;


public class Text1 {

	/**
	 * @param args
	 */
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner in = new Scanner(System.in);
		int a =in.nextInt();
		int b =in.nextInt();
		int c =in.nextInt();
		int max;
		if(a>b){
			if(a>c)
				max=a;
			else
				max=c;
		}
		else{
			if(b>c)
				max=b;
			else
				max=c;
		}
		System.out.println(max);
	}

}
import java.util.Scanner;
