}
public void sety(String m)
{
this.y = m ;
}
}
public class a
{
x ax = new x();
ax.sety("Hai");
}
public class z
{
a az = new a();
System.out.println(za.ax.gety()); //null Pointer exeption
}
Correct code for class a and claas z as follows -
-
-
public class Z {
-
public static void main(String a[]){
-
A az = new A();
-
System.out.println(az.ax.getY()); //null Pointer exeption
-
}
-
}
-
-
class A
-
{
-
X ax;
-
A(){
-
ax = new X();
-
ax.setY("Hai");
-
}
-
-
}
-
-
-
class X
-
{
-
private String y;
-
-
public String getY()
-
{
-
return y;
-
}
-
-
public void setY(String m)
-
{
-
this.y = m ;
-
}
-
-
}
-
-
Now I think urn code will compile and run...
