Groovy相等方法

name1="Michael"name2=new String("Michael")name3=name2PRintln name1 == name2 // trueprintln name2 == name3 // trueprintln name1.is(name2) // falseprintln name2.is(name3) // true2、equals方法
class A {	boolean equals(other) {		println "equals called"		true	}}new A() == new A() // equals called3、如果實現了Comparable接口，==會被映射到該類的compareTo()方法。
class A implements Comparable {	boolean equals(other) {		println "equals called"		true	}		int compareTo(other) {		println "compareTo called"		return 1	}}new A() == new A() // compareTo called
