Here is an example of finding sum and average of array of prime numbers
***
int[] arr = {2, 3, 5, 7, 11, 13, 17, 19, 23, 29}; // array of prime no.
int n = 4; // nth prime
int prime = arr[n-1]; // arrays are zero-indexed
int sum = Arrays.stream(arr).limit(n).sum(); // sum of the first n primes in the array
double average = (double) sum / n; // average of the first n primes in the array
***

Try this code:

You haven't implemented if block correctly. Use Opening and closing curly brackets

***
let x = 0;

while(x < 10)
{
console.log(x);
if(x == 5) {
break;
}
x++;
}

***// defining a function
function he\lloJS() {
console.log("Hello World!");
}

// calling the function
he\lloJS()***

Start by learning a programming language following tutorials on Studytonight.

You have to use **teaHour%4** instead of **teaHour** like shown in the following code.

***function teaBreak(){
console.log("Start making tea");
console.log("Tea ready");
console.log("Enjoy the tea");
}

let teaHour;

for(teaHour=1; teaHour<=12; teaHour++)
{
if(teaHour%4 == 0)
{
teaBreak();
}

Hi Sumit, The contents of style tag should be like this.
***@media (min-width: 550px) {
body {
font-size:25px;
}
}

Hi there, Thanks for pointing it out. We will fix the Lesson. For now you can use this solution to move forward.
***let player = {
name: "default_name",
weapon: "Pistol",
exp: "Pro",

// defining method
setName: function(name) {
this.name = name;
},
getName: function() {
return this.name;
},
showInfo: function() {
console.log(`${this.getName()} uses ${this.weapon} and is ${this.exp} level player in STBattleRoyal`);
}
};

player.setName("John Wick");
player.showInfo();***

Hi, Please specify the Lesson, Level and the error you got while submitting. Thanks.
