Method Detail

setText

public void setText(String Text)

indexOf

public int indexOf(String searchText)

Returns the index within this string of the first occurrence of the specified substring. The integer returned is the smallest value k such that:

 this.startsWith(str, <i>k</i>)
 

is true.

Parameters:

str - any string.

Returns:

if the string argument occurs as a substring within this object, then the index of the first character of the first such substring is returned; if it does not occur as a substring, -1 is returned.

Throws:

NullPointerException - if str is null.

indexOf

public int indexOf(String searchText,
                   int fromIndex)

Returns the index within this string of the first occurrence of the specified substring, starting at the specified index. The integer returned is the smallest value k such that:

 this.startsWith(str, <i>k</i>) && (<i>k</i> >= fromIndex)
 

is true.

There is no restriction on the value of fromIndex. If it is negative, it has the same effect as if it were zero: this entire string may be searched. If it is greater than the length of this string, it has the same effect as if it were equal to the length of this string: -1 is returned.

Parameters:

str - the substring to search for.

fromIndex - the index to start the search from.

Returns:

If the string argument occurs as a substring within this object at a starting index no smaller than fromIndex, then the index of the first character of the first such substring is returned. If it does not occur as a substring starting at fromIndex or beyond, -1 is returned.

Throws:

NullPointerException - if str is null

replace

public void replace(String oldText,
                    String newText,
                    int fromIndex)

replaces the provided new text with the old text, the operation will take place on the first occurance for the old text after the given index

Parameters:

oldText - The old text to be replaced

newText - The new text

fromIndex - The starting position

Throws:

NullPointerException - if either texts are null

replace

public void replace(String oldText,
                    String newText)

replaces the provided new text with the old text, the operation will take place on the first occurance for the old text

Parameters:

oldText - The old text to be replaced

newText - The new text

Throws:

NullPointerException - if either texts are null

replaceAll

public int replaceAll(String oldText,
                      String newText)

replaces the provided new text with every occurance for the old text

Parameters:

oldText - The old text to be replaced

newText - The new text

Returns:

the number of the occured replace times, -1 in when no replace took place

Throws:

NullPointerException - if either texts are null

occuranceNo

public int occuranceNo(String searchText)

searches the gievn text and returns the number of occurances

Parameters:

searchText - The text to search for

Returns:

the number of the occurance , -1 in when no occurance exist

Throws:

NullPointerException - if searchTexts is null

toString

public String toString()

returns the text after processing

Overrides:

toString in class Object

Returns:

resultant text
