How to allocate 1MB in Java

Answer 1

public class AllocateMemory {
    public static void main(String[] args) {
        // Allocates 1 MB = 1,048,576 bytes
        byte[] oneMB = new byte[1024 * 1024]; 

        // initialize the array
        for (int i = 0; i < oneMB.length; i++) {
            oneMB[i] = 0; // Initialize all bytes to 0
        }

        System.out.println("1 MB of memory allocated successfully!");
    }
}

 
 
/*
run:
 
1 MB of memory allocated successfully!
 
*/
