在Java中,三元组(Triple)是一种数据结构,用于存储三个相关的值。虽然Java没有内置的三元组类型,但我们可以使用自定义类或者其他数据结构来实现这个功能。以下是一些创新的使用三元组的方法:
public class Triple<A, B, C> {
public final A first;
public final B second;
public final C third;
public Triple(A first, B second, C third) {
this.first = first;
this.second = second;
this.third = third;
}
}
public Triple<Integer, Integer, Integer> exampleMethod() {
int a = 1;
int b = 2;
int c = 3;
return new Triple<>(a, b, c);
}
public class Point3D {
public final double x;
public final double y;
public final double z;
public Point3D(double x, double y, double z) {
this.x = x;
this.y = y;
this.z = z;
}
}
public class MetadataTriple {
public final String key;
public final int value;
public final boolean isActive;
public MetadataTriple(String key, int value, boolean isActive) {
this.key = key;
this.value = value;
this.isActive = isActive;
}
}
public class DateTriple {
public final int year;
public final int month;
public final int day;
public DateTriple(int year, int month, int day) {
this.year = year;
this.month = month;
this.day = day;
}
}
这些只是使用三元组的一些创新用法。你可以根据需要创建自己的三元组类,以满足特定的需求。
