Hashmap and finding data with a prompt
When I run choice == 2 I'm suppose to a an out.println back finding a product.
but I get Null for all the values.
Can someone help me with this
class Computer_listing{
private String id;
private String name;
privateint harddrive;
privateint memory;
privatefloat speed;
public Computer_listing(String idx){
this.id = idx;
}
public Computer_listing(String cd, String cn,int hd,int me,
float sp){
this.id = cd;
this.name = cn;
this.harddrive = hd;
this.memory = me;
this.speed = sp;
}
public String getId(){
return this.id;
}
public String getName(){
return this.name;
}
publicint getHardrive(){
return this.harddrive;
}
publicint getMemory(){
return this.memory;
}
publicfloat getSpeed(){
return this.speed;
}
publicvoid setId(String cd){
this.id = cd;
}
publicvoid setName(String cn){
this.name = cn;
}
publicvoid setHarddrive(Integer hd){
this.harddrive = hd;
}
publicvoid setMemory(Integer me){
this.memory = me;
}
publicvoid setSpeed(float sp){
this.speed = sp;
}
}

}// close the if loop
