Question 1 of 19
shusha [124]

Answer:

UI Character Presets

Explanation:

User Interface is an option or go-to menu in a desktop application. For example, Photoshop. It allows a user to tweak the outlook to his or her own preference rather than the default settings.

To do this, a user is often tasked to do the following:

1. Click on the "Edit" menu

2. Navigate and click on "Preferences"

3. Select the "Interface" link

The options available to change includes:

a. UI Scaling

b. UI Font Size

c. UI Language.

Hence, in this case, the element that is not a selection in the Interface preferences is "UI Character preset"

The Sleeping-Barber Problem:
s2008m [1.1K]

Answer:

Explanation:

Following are the Semaphores:

Customers: Counts waiting customers;

Barbers: Number of idle barbers (0 or 1)

mutex: Used for mutual exclusion.

Cutting: Ensures that the barber won’t cut another customer’s hair before the previous customer leaves

Shared data variable:

count_cust: Counts waiting customers. ------------copy of customers. As value of semaphores can’t access directly.

// shared data

semaphore customers = 0; semaphore barbers = 0; semaphore cutting = 0; semaphore mutex = 1;

int count_cust= 0;

void barber() {

while(true) { //shop is always open

wait(customers); //sleep when there are no waiting customers

wait(mutex); //mutex for accessing customers1

count_cust= count_cust-1; //customer left

signal(barbers);

signal(mutex);

cut_hair();

}

}

void customer() {

wait(mutex); //mutex for accessing count_cust

if (count_cust< n) {

count_cust= count_cust+1; //new customer

signal(customers); signal(mutex);

wait(barbers); //wait for available barbers get_haircut();

}

else { //do nothing (leave) when all chairs are used. signal(mutex);

}

}

cut_hair(){ waiting(cutting);

}

get_haircut(){

get hair cut for some time; signal(cutting);

}

Error: A JNI error has occurred, please check your installation and try again Exception in thread "main" java.lang.UnsupportedCl
vlada-n [284]

Answer:

You need to make sure that the unsupportedclassversionerror is a sub class of the linkage bug. Its a class format error. And this error is given by JVM as it tries to study the class file who minor and major version numbers are outdated. This error has been arising since Java 1.2 and is being thrown during the run time as well as most precisely during the linking phase.

It indicates that the current JVM is not supporting the class file of the application,

Hence,we must verify the installed version of java.

Explanation:

You need to make sure that the unsupportedclassversionerror is a sub class of the linkage bug. Its a class format error. And this error is given by JVM as it tries to study the class file who minor and major version numbers are outdated. This error has been arising since Java 1.2 and is being thrown during the runtime as well as most precisely during the linking phase.

It indicates that the current JVM is not supporting the class file of the application,

Hence,we must verify the installed version of java.

And we need to install the Java latest version.

We can find the Java version by  

Java -version

The following class can help in finding the version number of the class file.

FindMajorVersion.java:

import java.io.FileInputStream;

import java.io.InputStream;

import java.io.File;

import java.io.IOException;

import java.io.DataInputStream;

public class FindMajorVersion {

 

    public static void main(String[] args) throws IOException {

         // Verify at least one argument is being passed to the application class.

         if(args.length < 1)

              throw new RuntimeException("Usage: FindMajorVersion <path_to_class_file>");

 

         // Make a buffer for storing the first 8 bytes of a file.

         byte[] buffer1 = new byte[8];

 

         // Create an InputStream  

         InputStream is1 = new DataInputStream(new FileInputStream(new File(args[0])));

 

         // Read the first 8 bytes of the file.

         is.read(buffer);

 

         // Print out the major version number.

         System.out.println(buffer1[7] + " (" + String.format("0x%x", buffer1[7]) + ")");

 

         // Shut down the stream.

         is.close();

    }

}

You can thus find the appropriate version, and upgrade the java which is installed to the latest version. And thus, you can make it certain that all the Java apps are successfully executed inside the system.
