java替换字符串中特定字符

public class Find
{
	public static void main(String args[]) {
		String key = "，";
		String str = "6，035，45545445，55464，6456";
		StringBuilder strBuilder = new StringBuilder(str);
		int a = str.indexOf(key);
		while (a != -1) {
			/*System.out.print(a + "\t");*/
			strBuilder.setCharAt(a, '|');
			a = str.indexOf(key, a + 1);
		}
		str=strBuilder.toString();
		System.out.println(str);
        
	}
}

运行结果：

编译的过程中如果报错，就另存为一下，选择一下文件编码类型
