Used for storing multiple boolean values into one int variable. This snippet checks the bit values set in SetAppUpdateAvailable.java
package com.nileshdeokar.healthapp;
public class GetAppUpdateAvailable {
private int updateValue = 0b0110;
private static final int UPDATE_AVAILABLE = 1;
private static final int UPDATE_COMPULSORY = 2;
public void getUpdateAvailable(){
boolean result = false;
result = (this.updateValue & (1 << UPDATE_AVAILABLE)) != 0;
// This is how above line will get executed
// result = (0b0010 & (0b0001 << 1)) != 0; // Do the Bitwise left shift by 1
// result = (0b0010 & (0b0010)) != 0; // Do the Bitwise AND
// result = (0b0010 != 0); // Compare output with 0
// result = true;
}
public void getUpdateCompulsary(){
boolean result = false;
result = (this.updateValue & (1 << UPDATE_COMPULSORY)) != 0;
// This is how above line will get executed
// result = (0b0110 & (0b0001 << 2)) != 0; // Do the Bitwise left shift by 2
// result = (0b0110 & (0b0100)) != 0; // Do the Bitwise AND
// result = (0b0100 != 0); // Compare output with 0
// result = true;
