Answer:

Output: The question segment gives the following output--

1) 6

2) 5

3) JAVA!  

4) i love

5) I LOVEjava!

Explanation:

  1. "1) 6" comes because "6" is the length of "I LOVE" which is the value of "x" variable and "x.length( )" statement gives the length of the value of "x" variable which is stored on "a" variable and "a" will be printed with "1)" symbol.
  2. "2) 5" comes because "5" is the length of "java!" which is the value of "y" variable and "y.length( )" statement gives the length of the value of "y" variable which is stored on "b" variable and "b" will be printed with "2)" symbol.
  3. "3) JAVA! " comes because "JAVA!" is the upper case letter of "java!" which is the value of "y" variable and "y.toUpperCase( )" statement change the value from lower case to uppercase of the value of "y" variable which is stored on "c" variable and "c" will be printed with "3)" symbol.
  4. "4) i love " comes because "i love" is the lower case letter of "I LOVE" which is the value of "x" variable and "x.toLowerCase( )" statement change the value from uppercase to lowercase of the value of "x" variable which is stored on "d" variable and "d" will be printed with "4)" symbol.
  5. "5) I LOVEjava! " comes because " I LOVEjava! " is the mixed value of the "x" and "y" variable. It prints because "x.concat(y);" statement combines the x and y value and stored in an "e" variable and "e" will be printed with "5)" symbol.

Answers

Answer:

a. If the read is successful, the number of bytes read is returned.

b. If the end of file is encountered, 0 is returned.

Explanation:

A read function is one of the functions used in computer programming. A read function is used to read an information or data that was written before into a file.

If any portion of a regular file before to the end of file has not been written and the end of file is encountered the read function will return the bytes with value 0.

If read function has read some data successfully, it returns the number of bytes it read.

Write the code for invoking a static method named sendDouble, provided by the DataTransmitter class. There is one double argument for this method. Assume that a double variable called x has already been declared and initialized to some value. Use this variable's value as an argument in your method invocation.

Answers

Answer:

The program to this question as follows:

Program:

public class DataTransmitter //defining class

{

double x=3.0; //define variable x.  

public static void sendDouble(double x) //define method sendDouble.

{

x=9.6; //change variable value

System.out.print("The value of x variable is :"+x); //print value.

}

public static void main(String[] args) //define main method

{

sendDouble(0.0); //calling function

}

}

Output:

The value of x variable is :9.6

Explanation:

The explanation of the above java program can be define as follows:

  • In the above java program a class is define that is "DataTransmitter" inside a class a double variable that is x is define which contain a double value that is "3.0".
  • In this class, a static method "sendDouble()" is defined. in the method, a double parameter is passed. inside a method, we change the variable value and print its value.
  • In main method is a sendDouble() function is called. In calling time a double value is passed in the function parameter.
