求正则表达式匹配求出下列字符串中数值？高手进！

Question

字符串为：
HeapMemoryUsage: javax.management.openmbean.CompositeDataSupport(compositeType=javax.management.openmbean.CompositeType(name=java.lang.management.MemoryUsage,items=((itemName=committed,itemType=javax.management.openmbean.SimpleType(name=java.lang.Long)),(itemName=init,itemType=javax.management.openmbean.SimpleType(name=java.lang.Long)),(itemName=max,itemType=javax.management.openmbean.SimpleType(name=java.lang.Long)),(itemName=used,itemType=javax.management.openmbean.SimpleType(name=java.lang.Long)))),contents={committed=6496256, init=0, max=66650112, used=4241424})
NonHeapMemoryUsage: javax.management.openmbean.CompositeDataSupport(compositeType=javax.management.openmbean.CompositeType(name=java.lang.management.MemoryUsage,items=((itemName=committed,itemType=javax.management.openmbean.SimpleType(name=java.lang.Long)),(itemName=init,itemType=javax.management.openmbean.SimpleType(name=java.lang.Long)),(itemName=max,itemType=javax.management.openmbean.SimpleType(name=java.lang.Long)),(itemName=used,itemType=javax.management.openmbean.SimpleType(name=java.lang.Long)))),contents={committed=35618816, init=33718272, max=121634816, used=21805632})
ObjectPendingFinalizationCount: 0
需要分别匹配求出红色字符串中显示的数字。
要求结果为：
6496256
4241424
66650112
即可。
可以分别提供三个正则表达式进行多次匹配求出。

Answer 2

有点不显示  最后一行是{committed=35618816, init=33718272, max=121634816, used=21805632}) 拿什么匹配啊 能想到的就是拿这四个单词匹配。。

Answer 6

pattern="({committed=\\d+, init=\\d+, max=\\d+, used=\\d+})";\\这个就是模式字符串
 Pattern p = Pattern.compile("pattern");
 Matcher m = p.matcher(str);//str是上面那一堆字符串
 boolean b = m.matches();
  if(b){
    int count= m.groupCount();
    while(count>0){
      String  s=m.group(count);//这个s就是上面匹配的字符串
         //这里分割处理上面那个字符串
        count--;//循环处理其他的
    }
 }
