My major/JAVA
1. Create target class for sorting and define compareTo() function
class TargetClass implements Comparable{
int id;
String name;
public TargetClass(int id, String name){
id = id;
name = name;
}
public int compareTo(Object o){
TargetClass tc = (TargetClass)o;
if(this.id > tc.id)
return 1;
else if(this.id == tc.id)
return 0;
else
return -1;
}
}
2. sort
public class mainClass{
public static void main(String argv[]){
Vector<TargetClass> vec = new Vector<TargetClass> ();
for(int i=10; i>0; i--){
TargetClass item = new TargetClass(i, "jo"+i);
vec.add(item);
}
Collections.sort(vec);
}
}
class TargetClass implements Comparable{
int id;
String name;
public TargetClass(int id, String name){
id = id;
name = name;
}
public int compareTo(Object o){
TargetClass tc = (TargetClass)o;
if(this.id > tc.id)
return 1;
else if(this.id == tc.id)
return 0;
else
return -1;
}
}
2. sort
public class mainClass{
public static void main(String argv[]){
Vector<TargetClass> vec = new Vector<TargetClass> ();
for(int i=10; i>0; i--){
TargetClass item = new TargetClass(i, "jo"+i);
vec.add(item);
}
Collections.sort(vec);
}
}
