    public static void main(String args[]){
        Scanner sc=new Scanner(System.in);
        System.out.println("Enter amount of heat transferred (in joules)");
        float heat=sc.nextFloat();
        System.out.println("Enter rise (difference) in temperature");
        float temperature=sc.nextFloat();
    
        System.out.println("Amount of heat supplied "+heat);
        System.out.println("Rise in temperature "+temperature);
         float heatCapacity;
         heatCapacity = heat/temperature;

        System.out.println("Heat Capacity = "+heatCapacity+"j/c");

Java program for words which do not contain any vowels in a sentence

How to write a java program words which do not contain any vowels in a sentence using java

 
Here we are going to see a java program to input a sentence and print those word which
  do not contain any vowels and simultaneously count and print those words.  
 

•   First read a sentence
•   Now using StringTokenizer get each word
•   Now from each word check word contains any vowel or not 

import java.util.*;
class Highest{
 public static void main(String args[]){
    
     //read a sentence
     System.out.println("enter a sentence");
     Scanner sc=new Scanner(System.in);
     String sentence=sc.nextLine();
     StringTokenizer st=new StringTokenizer(sentence);
     String word;
 
     int index=-1,count=0;
     char vowel[]={'a','e','i','o','u'};
     System.out.println("Words which do not contain vowels are ");

     // iterating each word
     while(st.hasMoreTokens()){
        word=st.nextToken();

        // check word contains any vowel or not        

        for(char c:vowel){
            index=-1;
            index = word.indexOf(c);
            if(index>=0) break;
        }
        if(index==-1){
            System.out.println(word);
            count++;
        }

    
     }//while closing
     System.out.println("Total number of words which do not contain vowels are "+count);
    }
 }

Input runs scored in a cricket and display the highest

 Input runs scored in a cricket and display the highest

In this java program we are going to see the runs scored by 11 batsman
in a cricket match and display the highest score among them.
so first read the runs scored by 11 batsman in a match and find the highest score.



import java.util.*;
class Highest{
 public static void main(String args[]){
    int score[]=new int[11];  
    Scanner sc=new Scanner(System.in);
    //reading the runs scored by individual players
    for(int i=0;i<11;i++){
        System.out.println("Enter runs scored by player "+i+1+".");
        score[i]=sc.nextInt();
    }
    //displaying the runs scored by individual players
    for(int i=0;i<11;i++){
       System.out.println("Runs scored by player"+i+1+" is "+score[i]);
    }
    //finding maximum
    int max=0;
    for(int i=0;i<11;i++){
       if(score[i]>max)
           max=score[i];
       }
    System.out.println("Highest scored runs = "+max);
    }
}

 

output:
