I'm trying to access an array in the object "other," but I can't figure out how to access the variable. This is what I have so far:
public void union(DataSet other)
{
DataSet temp = new newdataexp();
temp = other;
}
I haven't been able to figure out how to access the variable, even when I create a method in the class that returns the variable and then trying to call it from this method union.
I have this method, and am trying to do: String[][] temp = other.getdata(), but the compiler says that it cannot find symbol: method getdata().
public String[][] getdata() {
return filedata;
}
I don't know if I good understand you question but to access a variable in another object of the same class just try this:
class MyClass {
private int[] myArray = new int[10];
public void myMethod(MyClass myClass) {
// you can in this way:
// int[] tempArray = myClass.myArray
// but this is better:
int[] tempArray = myClass.getMyArray();
}
public int[] getMyArray() {
return myArray;
}
}
Edited:
But if you want to make union better extract union method outside class, create method:
public static MyObject union(MyObject myObjectFirst, MyObject myObjectSecond) {
...
}
只要方法返回,就用String,int等替换数据类型。
datatype mynewdata = (datatype)other.getMeMyArray();
