 There's no method or operator to do this in Java, so you have to do it yourself.
-<lang java5>public static String repeat(String str, int times){
+<lang java5>public static String repeat(String str, int times) {
-   StringBuilder ret = new StringBuilder();
+    StringBuilder sb = new StringBuilder(str.length() * times);
-   for(int i = 0;i < times;i++) ret.append(str);
+    for (int i = 0; i < times; i++)
-   return ret.toString();
+        sb.append(str);
+    return sb.toString();
 }

-  System.out.println(repeat("ha", 5));

 Or even shorter:
-<lang java5>public static String repeat(String str, int times){
+<lang java5>public static String repeat(String str, int times) {
    return new String(new char[times]).replace("\0", str);
 }</lang>
