Java-成绩判断

简单的多重if

package rydttdg;

public class java09 {
	public static void main(String[] args) {
		int a=60;
		if(a>80) {
			System.out.println("成绩为优");
			
		}else if(a>70){
			System.out.println("成绩为良");
		}else if(a>60) {
			System.out.println("成绩为中");
		}else if(a<=60) {
			System.out.println("成绩为差");
		}	
				
    }
}
