访问 JVM

访问 Java 类

_console.log(StringBuilder::class.java)

$console.log(StringBuilder)

let StringBuilder = $java.loadClass("java.lang.StringBuilder")
$console.log(StringBuilder)

local StringBuilder = _java:loadClass("java.lang.StringBuilder")
_console:log(StringBuilder)

<?php
// java_class 通过类名加载类
$class = java_class("java.lang.System");
$console->log($class);

StringBuilder = _java.loadClass("java.lang.StringBuilder")
_console.log(StringBuilder)

StringBuilder = java.lang.StringBuilder
$console.log(StringBuilder)

创建 Java 对象

_console.log(StringBuilder("Hello World"))

$console.log(new StringBuilder("Hello World"))

let StringBuilder = $java.loadClass("java.lang.StringBuilder")
$console.log(new StringBuilder("Hello World"))

local StringBuilder = _java:loadClass("java.lang.StringBuilder")
_console:log(StringBuilder("Hello World"))

<?php
// 通过 java(类名,构造方法参数) 创建对象
$a = java("java.util.Date", 123);
$console->log($a->time);

StringBuilder = _java.loadClass("java.lang.StringBuilder")
_console.log(StringBuilder("Hello World"))

StringBuilder = java.lang.StringBuilder
$console.log(StringBuilder.new("Hello World"))

调用 Java 对象方法

val sb = StringBuilder("Hello World")
sb.append(",kotlin!")
_console.log(sb.toString())

def sb = new StringBuilder("Hello World")
sb.append(",groovy!")
$console.log(sb.toString())

let StringBuilder = $java.loadClass("java.lang.StringBuilder")
let sb = new StringBuilder("Hello World")
sb.append(",js!")
$console.log(sb.toString())

local StringBuilder = _java:loadClass("java.lang.StringBuilder")
local sb = StringBuilder("Hello World")
sb:append(",lua!")
_console:log(sb:toString())

<?php
$sb = java("java.lang.StringBuilder", "Hello World");
$sb->append(",php!");
$console->log($sb->toString());

StringBuilder = _java.loadClass("java.lang.StringBuilder")
sb = StringBuilder("Hello World")
sb.append(",python!")
_console.log(sb.toString())

StringBuilder = java.lang.StringBuilder
sb = StringBuilder.new("Hello World")
sb.append(",ruby!")
$console.log(sb.toString())

调用 Java 对象属性

import com.m8test.script.core.impl.JavaTypeTester

_console.log(JavaTypeTester().OBJECT_FIELD)

import com.m8test.script.core.impl.JavaTypeTester

$console.log(new JavaTypeTester().OBJECT_FIELD)

$console->log($a->OBJECT_FIELD);

JavaTypeTester = _java.loadClass("com.m8test.script.core.impl.JavaTypeTester")
_console.log(JavaTypeTester().OBJECT_FIELD)

java_import "com.m8test.script.core.impl.JavaTypeTester"
jtt = JavaTypeTester.new
$console.log(jtt.OBJECT_FIELD)

调用 Java 静态方法

_console.log(System.currentTimeMillis())

$console.log(System.currentTimeMillis())

let System = $java.loadClass("java.lang.System")
$console.log(System.currentTimeMillis())

local System = _java:loadClass("java.lang.System")
_console:log(System:currentTimeMillis())

<?php
// 方法二: java_class() 方法导入类后通过 -> 调用
$class = java_class("java.lang.System");
//# System.currentTimeMillis();
$console->log($class->currentTimeMillis());
$console->log($class::currentTimeMillis());

System = _java.loadClass("java.lang.System")
_console.log(System.currentTimeMillis())

System = java.lang.System
$console.log(System.currentTimeMillis())

调用 Java 静态属性

import com.m8test.script.core.impl.JavaTypeTester

_console.log(JavaTypeTester.STATIC_FIELD)

import com.m8test.script.core.impl.JavaTypeTester

$console.log(JavaTypeTester.STATIC_FIELD)

$console.log(JavaTypeTester.STATIC_FIELD)

local JavaTypeTester = _java:loadClass("com.m8test.script.core.impl.JavaTypeTester")
_console:log(JavaTypeTester.STATIC_FIELD)

<?php

# System.in 静态常量
$in = $class::in;
$console->log(gettype($in));
$JavaTypeTester = java_class("com.m8test.script.core.impl.JavaTypeTester");
// 静态变量, 反射调用
$v = $reflectors->reflect($JavaTypeTester)->getField(null, function ($f) {
    $f->setName("STATIC_FIELD");
});
$console->log(gettype($v));

JavaTypeTester = _java.loadClass("com.m8test.script.core.impl.JavaTypeTester")
