rite a Java program that has the user enter integer values, one after the other, until they enter the value $1.$ Once the user enters $1,$ the program outputs the total and the average of all the values entered $($not including the value $1).$ You may call the method "keyboard.nextInt$()"$ which returns the integer entered by the user on the keyboard. Here are two sample runs:

Sample Run #$1$:

Enter an integer: $7$

Enter an integer: $13$

Enter an integer: $4$

Enter an integer: $-1$

The sum is $24.$

The average is $8.$

Sample Run #$1$:

Enter an integer: $50$

Enter an integer: $10$

Enter an integer: $30$

Enter an integer: $20$

Enter an integer: $60$

Enter an integer: $40$

Enter an integer: $-1$

The sum is $210.$

The average is $35.$
