Java programs
using scanner class
Write a program to accept three sides of a triangle as parameter and check whether it can form a triangle or not if it forms a triangle check whether it is an acute angle obtuse angle a right angled triangle
Write a program to accept marks obtained by a student in Computer Science and print the grade accordingly
Marks
Above 90. A
70 to 89. B
50 to 69. C
below 50. D
Answers
For the first Program:
import java.util.*;
public class Triangle
{
public static void main(String args[])
{
Scanner in =new Scanner(System.in);
float a,b,c,d,e,f;
System.out.println("Enter the length of the sides of the triangle");
a=in.nextFloat();
b= in.nextFloat();
c=in.nextFloat();
System.out.println("Enter the measure of the angles");
d=in.nextFloat();
e=in.nextFloat();
f=in.nextFloat();
if(a+b>c && a+c>b && c+b>a)
{
System.out.println("Triangle is possible");
else
System.out.println("Triangle is not possible");
}
if(d>90 || e>90 ||f>90)
{
System.out.println("Its an obtuse-angled triangle");
elseif(d=90||e=90 || f=90)
{
System.out.println("Its a right-angled triangle");
}
else
System.out.println("Its an acute-angled triangle");
}
}
}

For the second program:
import java.util.*;
public class Grade
{
public static void main(String args[])
{
Scanner in =new Scanner(System.in);
float m;
char "A","B","C","D";
System.out.println(" Enter the mark obtained by the student");
m =in.nextFloat();
if(m>=90)
{
System.out.println("The grade is =" + "A");
elseif(90> M>=70)
{
System.out.println("The grade is=" +"B");
}
elseif(70>M>=50)
{
System.out.println("The grade is =" +"C");
}
else
System.out.println("The grade is="+"D");
}
}
}
