Question

USE JAVA FOR:
1) Count the letters in string.
2) Print random number.​

Answer 1

Solution:

This is written in Java.

1.

public class Program {

public static void main(String[] args) {

String s="purveshKolhe0001";

int count=0;

for(int i=0;i<s.length();i++){

char x=s.toLowerCase().charAt(i);

if (x>='a' && x<='z')

count++;

}

System.out.println("Number of letters\nin \""+s+"\" is: "+count);

}

}

2.

public class Program {

public static void main(String[] args) {

System.out.println(Math.random());

}

}

Note:

• For the first question, I have counted only the letters (a to z).
• For the second question, use Math.random() function. It generates random decimal number between 0 and 1.

Output:

1.

Number of letters

in "purveshKolhe0001" is 12

2.

Any random value.
