Java中printf

java 1.8

int id = 1;
int kind =2;
String name = "%gaaa"; // %g被误解为格式化字符

System.out.printf("name: %s id:%2d" + " kind " + kind +" \n", name , id); //正确

System.out.printf("name" + name, "id:%2d" +" \n" , id); //报错

// 运行时报错

Exception in thread "main" java.util.IllegalFormatConversionException: g != java.lang.Integer

总结: %xx 后不能再接String
