Question

Fall 2019 1. Assign each line to a variable and write the passage from Shakespeare's Sonnet #52 to console (Careful about line breaking): Blessed are you whose worthiness gives scope, Being had, to triumph; being lacked, to hope. 2. Create two integer variable, width and height. Write them to console in similar format, i.e. Width of rectangle is 5. 3. Update width and height variable with another value, and write them to console in similar format above. 4. Calculate the area of rectangle that would be made by these two vari- ables. Write it to console in similar format, i.e. Area of rectangle is 25. 5. Increase width variable with 10 and decrease height variable with 3 by using assignment operator Recalculate the area of rectangle and write it to console in similar format above. 6. Create two different variable in data type below: • byte, short, int, long • float, double .char, String • boolean 7. Calculate the expression: 10+ (7%3) - + is an example of assignment operator, e.g. x + 5

We should use “Java” language. Java Eclipse :)

Answers:

1.

String line1,line2;

line1="Blessed are you whose worthness gives scope,\n";
line2="Being had, to triumph; being lacked, to hope.";

System.out.println(line1+""+line2);

2.

int width,height;
width=5;
height=5;
System.out.println("Width of rectangle is "+width);
System.out.println("height of rectangle is "+height);

3.

width=4;
height=4;
System.out.println("Width of rectangle is "+width);
System.out.println("height of rectangle is "+height);

4.

System.out.println("Area of rectangle is "+(width*height));

5.

width += 10;
height -= 3;
System.out.println("Area of rectangle is "+(width*height));

6.

byte by1[],by2[];
short s1,s2;
int i1,i2;
long l1, l2;
float f1,f2;
double d1,d2;
char ch1, ch2;
String str1,str2;
boolean b1,b2;

7.

System.out.println(10+(7%3)-12/8);

Program:

public class Program
{
public static void main(String args[])
{
//1.

String line1,line2;

line1="Blessed are you whose worthness gives scope,\n";
line2="Being had, to triumph; being lacked, to hope.";

System.out.println(line1+""+line2);

//2.

int width,height;
width=5;
height=5;
System.out.println("Width of rectangle is "+width);
System.out.println("height of rectangle is "+height);

//3.

width=4;
height=4;
System.out.println("Width of rectangle is "+width);
System.out.println("height of rectangle is "+height);

//4.

System.out.println("Area of rectangle is "+(width*height));

//5.

width += 10;
height -= 3;
System.out.println("Area of rectangle is "+(width*height));

//6.

byte by1[],by2[];
short s1,s2;
int i1,i2;
long l1, l2;
float f1,f2;
double d1,d2;
char ch1, ch2;
String str1,str2;
boolean b1,b2;

//7.

System.out.println("10+(7%3)-12/8 = "+(10+(7%3)-12/8));
}
}
