What it do? x<myArr.length;

its part of this code int [ ] myArr = {6, 42, 3, 7}; int sum=0; for(int x=0; x<myArr.length; x++) { sum += myArr[x]; } System.out.println(sum); // 58

This case: x=0 myArr.length = 4 //the size of the array In the loop: Iteration 0: 0<4 = true x=0+1 //1 Iteration 1: 1<4 = true x=1+1 //2 Iteration 2: 2<4 = true x=2+1 //3 Iteration 3: 3<4 = true x=3+1 //4 Iteration 4: 4<4 = false End of the loop.

It represents the condition for the loop to be executed. While that condition is true, the loop continues; if the condition is false, the loop ends.

This is called loop. The meaning of myArr.length is the total length that is in inside the array i.e. { }. So, whenever we try to sum all the number inside the array, we specially put .length method on it. if we do not want to loop all number then your code will be like for(int x = 0; x< 1; x++) Overall, If you want to loop all number inside the array, because we are lazy to count all the number then we put .lenght.
