Write a method called classAttendence() that creates a 10-by-10 two-dimensional array and asks for user input to populate it wit
gladu [14]

Answer:

The method written in Java is as follows:

public static void classAttendance(){

   Scanner input = new Scanner(System.in);

   String[][] names = new String[10][10];

   for(int i =0;i<10;i++){

    for(int j =0;j<10;j++){

       System.out.print("Student Name: "+(i+1)+" , "+(j+1)+": ");

       names[i][j] = input.nextLine();        

    }  

   }

}

Explanation:

This defines the classAttendance() method

public static void classAttendance(){

   Scanner input = new Scanner(System.in);

This declares the 2D array of 10 by 10 dimension as string

   String[][] names = new String[10][10];

This iterates through the rows of the array

   for(int i =0;i<10;i++){

This iterates through the columns of the array

    for(int j =0;j<10;j++){

This prompts user for student name

       System.out.print("Student Name: "+(i+1)+" , "+(j+1)+": ");

This gets the student name from the user

       names[i][j] = input.nextLine();        

    }  

   }

The method ends here

}

What output is produced by the following code? Integer first = new Integer(7); Integer second = first; if (first == second) Syst
fenix001 [56]

Answer:

The correct output of this question is  "Sneezy Sleepy".

Explanation:

In the given code firstly we create the object of the integer class that is first in this we pass the integer value that is 7. Then we declare another second integer variable is this variable we pass object as a reference. Then we use the two conditional statements. In the first, if block we check that the object of the class is equal to the reference variable. If it is true it prints Sneezy. otherwise, it will print Grumpy. In second if block we check that the object of the class is equal to the reference variable. but in this time we the equals() function it is the same as(==). If the condition is true it prints Sleepy. otherwise, it will print Doc. So the output of the code is Sneezy Sleepy.
