Boolean類型

package com.barcode.app;

public class ExternData
{  
    private static Boolean a = true;  

    public static Boolean getA() 
    {  
        return a;  
    }  

    public static void setA(Boolean a) 
    {  
        ExternData.a = a;  
    }  
}  

if (ExternData.getA())
        {
            ExternData.setA(false);
        }

String類型

public class Data{  
    private static String a =15083386523;  

    public static String getA() {  
        return a;  
    }  

    public static void setA(String a) {  
        Data.a = a;  
    }  
}  

    String str;
    Data.setA(String **);// String傳參
    str = Data.getA();//得到其值

數組類型

public class Data
{  
    private static int[] a;  

    public static int[] getA() 
    {  
        return a;  
    }  

    public static void setA(int[] a) 
    {  
        DataTest.a = a;  
    }
}
