[java] How to find integer array size in java

below is my code which is throwing error:

Cannot invoke size() on the array type int[]

Code:

public class Example{
int[] array={1,99,10000,84849,111,212,314,21,442,455,244,554,22,22,211};    
public void Printrange(){

for (int i=0;i<array.size();i++){
    if(array[i]>100 && array[i]<500)
{
System.out.println("numbers with in range ":+array[i]); 
}


}

Even i tried with array.length() it also throwing the same error. When i used the same with string_name.length() is working fine.

Why it is not working for an integer array?

There is no method call size() with array. you can use array.length

we can find length of array by using array_name.length attribute

int [] i = i.length;

public class Test {

    int[] array = { 1, 99, 10000, 84849, 111, 212, 314, 21, 442, 455, 244, 554,
            22, 22, 211 };

    public void Printrange() {

        for (int i = 0; i < array.length; i++) { // <-- use array.length 
            if (array[i] > 100 && array[i] < 500) {
                System.out.println("numbers with in range :" + array[i]);
            }
        }
    }
}

Integer Array doesn't contain size() or length() method. Try the below code, it'll work. ArrayList contains size() method. String contains length(). Since you have used int array[], so it will be array.length

public class Example {

    int array[] = {1, 99, 10000, 84849, 111, 212, 314, 21, 442, 455, 244, 554, 22, 22, 211};

    public void Printrange() {

        for (int i = 0; i < array.length; i++) {
            if (array[i] > 100 && array[i] < 500) {
                System.out.println("numbers with in range" + i);
            }
        }
    }
}

Array's has

array.length

whereas List has

list.size()

Replace array.size() to array.length

I think you are confused between size() and length.

(1) The reason why size has a parentheses is because list's class is List and it is a class type. So List class can have method size().

(2) Array's type is int[], and it is a primitive type. So we can only use length
