泛型类

[java]代码库

1.Student泛型类
package s0222泛型类;
//使用时确定类型,比如以下这个例子中,学生的成绩的类型组合可以是多种多样的
public class Student<T1,T2> {
	
        private T1  javaScore;
        private T2 oracleScore;
        
        
        
        public Student() {
		}

		public Student(T1 javaScore, T2 oracleScore) {
			this.javaScore = javaScore;
			this.oracleScore = oracleScore;
		}

		public T1 getJavaScore() {
			return javaScore;
		}


		public void setJavaScore(T1 javaScore) {
			this.javaScore = javaScore;
		}


		public T2 getOracleScore() {
			return oracleScore;
		}


		public void setOracleScore(T2 oracleScore) {
			this.oracleScore = oracleScore;
		}

		@Override
		public String toString() {
			return "Student [javaScore=" + javaScore + ", oracleScore="
					+ oracleScore + "]";
		}
		
		
}

2.测试类
package s0222泛型类;

public class Test {
	
	public static void  main(String [] args)
    {
    		Student<String,Integer> stu1=new Student<String,Integer>("17",3); //成绩类型是String 和Integer
    		System.out.println(stu1.toString());
    		
    		Student<Integer,Double> stu2=new Student<Integer,Double>(1,3.2);  //成绩类型是Integer和Double
    		System.out.println(stu2.toString());
    		
    }
}
