Java Utililty Methods String Repeat

String createRepeatedString(char c, int length)
Create a string of the same char

char[] vals = new char[length];
Arrays.fill(vals, c);
return String.valueOf(vals);

String deleteRepeatStr(String repeatStr, String separator)
delete this repeat character

if (repeatStr == null) {
 return null;
StringBuffer noRepeatStr = new StringBuffer();
String[] strElement = repeatStr.split(separator);
List strlist = new ArrayList();
for (int i = 0; i < strElement.length; i++) {
 if (!strlist.contains(strElement[i])) {
...

String repeat(String in, int count)
repeat

if ((in == null) || (count < 1))
 return "";
StringBuffer out = new StringBuffer();
for (int i = 0; i < count; i++) {
 out.append(in);
return out.toString();

String repeat(String item, int count)
Creates string where given item string is repeated count times.

StringBuilder result = new StringBuilder();
if (!isEmpty(item))
 for (int i = 0; i < count; i++)
 result.append(item);
return result.toString();

String repeat(String pattern, int count)
repeat

final StringBuilder builder = new StringBuilder();
for (int i = 0; i < count; i++) {
 builder.append(pattern);
return builder.toString();

String repeat(String s, int cnt)
Concatentate the given string cnt times

StringBuffer sb = new StringBuffer();
for (int i = 0; i < cnt; i++) {
 sb.append(s);
return sb.toString();

String repeat(String s, int times)
repeat

StringBuffer sb = new StringBuffer();
for (int i = 0; i < times; i++) {
 sb.append(s);
return sb.toString();

String repeat(String s, int times)
Create a string by repeating a substring by specified times.

return repeat(s, times, null);

String repeat(String s, int times)
Generate a string that repeats/replicates a string a specified number of times.

StringBuilder sb = new StringBuilder();
for (int i = 0; i < times; ++i) {
 sb.append(s);
return sb.toString();

String repeat(String str, int count)
repeat

if (count < 0)
 throw new IllegalArgumentException("count must be positive");
char[] chars = str.toCharArray();
char[] result = new char[chars.length * count];
int resultIdx = 0;
for (int i = 0; i < count; i++, resultIdx += chars.length)
 System.arraycopy(chars, 0, result, resultIdx, chars.length);
return new String(result);
