StringArray questions

[indianj]

Hello i need help with removing string. can someone please help me with my code.

------
<code>
public static StringArraySeq concatenation(StringArraySeq s1,StringArraySeq s2){

//StringArraySeq s1=new StringArraySeq();
//StringArraySeq s2=new StringArraySeq();
StringArraySeq longStringArraySeq = new StringArraySeq(s1.size()+s2.size());
//StringArraySeq longStringArraySeq = new StringArraySeq(100);
System.arraycopy(s1.data,0,longStringArraySeq.data,0,s1.size());
System.arraycopy(s2.data,0,longStringArraySeq.data,s1.size(),s2.size());
longStringArraySeq.manyItems = s1.size() + s2.size();
longStringArraySeq.currentIndex = longStringArraySeq.manyItems;

return longStringArraySeq;


}

/**
* Check if all the capacity has been consumed.
* @return
* boolean:
* true (if no space left) or false (if space is available)
*/
public boolean data1(){
return (manyItems == getCapacity() );
}


public boolean isEmpty(){
return (manyItems == 0);
}

/**
* Return a String displaying items in the sequence
* @return
* String: shows the elements in sequence in set format.
*/
public String toString(){

String sa = "";
//System.out.println( "Number.length = " + sa.length );
//System.out.println();

for (int i=0; i<manyItems; i++){
sa = sa + "\n" + data[i];
}
return sa;

}

public String getString(String[] arg){

return "";
//return ;

}


/**
* Print out a set representation of the sequence
*/
public void print(){
System.out.println(this);
}

public void addAfter(String element){
if( isEmpty() ){
data[0] = element;
currentIndex = 0;


}
// make sure there's enough room
else {
if( data1() ) ensureCapacity();
// increment currentIndex, and then put element
// at currentIndex
++currentIndex;
for( int i = manyItems; i > currentIndex; i-- ){
data[i] = data[i-1];
}
data[currentIndex] = element;
}
++manyItems;
//--manyItems;
}





public boolean removeCurrent(){
if( isEmpty())
return false;
else {
if( manyItems == currentIndex + 1){
--manyItems; // if pointing at last element in data.
--currentIndex;
}
else {
for( int i = currentIndex; i < manyItems; i++ )
data[i] = data[i+1];
--manyItems;
//--currentIndex;
}
}
return true;
}



public static void main (String [ ] args) {
System.out.println("..:: Welcome ::..");
System.out.println();

// double [] d={12.4, 16.9,7.3,4.8};
StringArraySeq sa=new StringArraySeq();

sa.addAfter("first");
sa.addAfter("second");
sa.addAfter("third");
// s.addBefore (11.5);
//sa.toString();
System.out.println(sa);
//sa.toString();

System.out.println();
System.out.println();
StringArraySeq s1=new StringArraySeq();
s1.addAfter("first");
s1.addAfter("second");
StringArraySeq s2=new StringArraySeq();
s2.addAfter("third");
s2.addAfter("fourth");
StringArraySeq bigS = StringArraySeq.concatenation(s1,s2);
System.out.println(bigS.toString());
bigS.removeCurrent("third");

}</code>

bigS.removeCurrent("third"); seem not working right.
