In Java, there is no global keyword, but we can use public static variable to referring a global variable.

For example :

package com.mkyong.example;

public class MagicUtils {

    public static final String NAME = "mkyong"; // global
    public static final int LUCKY_NUMBER = 7;   // global

}

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
