Answer:
Explanation:
The following code is written in Java. I recreated the entire Child class as described with the instance variables and the doubleWeight method. Then created the getter and setter methods for both the weight and height variables.
class Child {
double weight, height;
public double doubleWeight() {
double superWeight = weight * height;
return superWeight;
}
public double getWeight() {
return weight;
}
public void setWeight(double weight) {
this.weight = weight;
}
public double getHeight() {
return height;
}
public void setHeight(double height) {
this.height = height;
}
}
Answer:
Option (C) FAT32 File System Type
Explanation:
- FAT32 File System Type cannot be encrypted by the accounting users.
- FAT stands for File Allocation Table. It is a file system architecture.
- The File Allocation Table is an index table which contains the details about each cluster ( disk storage space ).
- By traversing the File Allocation Table, the operating system gets the details the file ( where it is located ) and the size of the file.
- The FAT32 file system contains more number of possible clusters.
- In this system, 32 bits are used to store the total number of possible clusters.
- In FAT32 file system, the transparent encryption is not supported.
- So, option (C) is correct.
- All other options are wrong options.
Answer is C
