方法练习：比较两个数字是否相同和求出1-100的累加和

比较两个数字是否相同

 System.out.println(issame(10,50));
    System.out.println(issame(45,45));

}

    public static boolean issame( int a, int b) {
    /*booLean same;
        if (a == b) {
        same = true;}else i
        same = false;}*/
         // boolean same = a == b ? true : false;
        // boolean same = a == b;
        return a == b;
    }
结果

false    //10,50不一样
true　　　//45，,45一样

 

求出1-100的累加和

    System.out.println(getsum());
}

public static int getsum(){
        int sum =0;
    for (int i = 1; i <= 100; i++) {
        sum+=i;
    }
    return sum;
}
结果

5050
