Java – Global variable examples
In Java, there is no global
keyword, but we can use public static
variable to referring a global variable.
For example :
MagicUtils.java
package com.mkyong.example;
public class MagicUtils {
public static final String NAME = "mkyong"; // global
public static final int LUCKY_NUMBER = 7; // global
}
JavaExample.java
package com.mkyong.example;
public class JavaExample {
public static void main(String[] args) {
System.out.println(MagicUtils.NAME);
System.out.println(MagicUtils.LUCKY_NUMBER);
}
}
Output
mkyong
7
