输入一个学生的成绩，如果学习成绩>=90分的同学用A表示，60-89分之间用B表示，60分以下的用C表示(10)

public static void main(String[] args){

Scanner scanner = new Scanner(System.in);

System.out.println(“请输入学生成绩：”);

Int grade = scanner.nextInt();

If(grade >=90){

System.out.println(‘A’);

}else if(grade >= 60){

System.out.println(‘B’);

}else{

System.out.println(‘C’);

}

编写一个java程序在屏幕上输出1!+2!+3!+……+10!的和(10)

public class test {

int sum = 0;

int res = 1;
for(int i = 1; i<=10;i++){

                         res = sum*i;
            sum += res;
        }
        System.out.println("1!+2!+3!+……+10!的和是" + sum);
    }
}

int [] arr1 = new int[3];

int [] arr2 = new int[4];

for(int i = 0;i <arr1.length;i++){

                    arr1[i] = (int)(Math.random()*10);

for(int i = 0;i <arr1.length;i++){

                    arr1[i] = (int)(Math.random()*10);

}

int[] arr3 = new int[arr1.length + arr2.length];

for (int i = 0; i < arr1.length; i++) {

    arr3[i] = arr1[i];

}

for (int i = 0; i < arr2.length; i++) {

    arr3[arr3.length+i-arr2.length] = arr2[i];

}

for(int i = 0;i < arr3.length - 1;i++){

    for(int j = 0;j <arr3.length - i - 1;j++){

        if(arr3[j] < arr3[j+1]){

            int temp = arr3[j];

            arr3[j] = arr3[j+1];

            arr3[j+1] = temp;

        }

    }

}

System.out.println("合并后的数组是：");

for(int v:arr3){

    System.out.print(v+"\t");
