java原子性变量 AtomicIntegerget(): 获取当前值。int value = atomicInteger.get();set(int newValue): 设置新值。atomicInteger.set(42);incrementAndGet(): 将当前值加一，并返回新值。int newValue = atomicInteger.incrementAndGet();decrementAndGet(): 将当前值减一，并返回新值。int newValue = atomicInteger.decrementAndGet();addAndGet(int delta): 将当前值加上指定增量，并返回新值。int newValue = atomicInteger.addAndGet(10);compareAndSet(int expect, int update): 如果当前值等于 expect，则将其更新为 update，并返回是否成功。boolean success = atomicInteger.compareAndSet(10, 20);AtomicLongget(): 获取当前值。long value = atomicLong.get();set(long newValue): 设置新值。atomicLong.set(100L);incrementAndGet(): 将当前值加一，并返回新值。long newValue = atomicLong.incrementAndGet();decrementAndGet(): 将当前值减一，并返回新值。long newValue = atomicLong.decrementAndGet();addAndGet(long delta): 将当前值加上指定增量，并返回新值。long newValue = atomicLong.addAndGet(50L);compareAndSet(long expect, long update): 如果当前值等于 expect，则将其更新为 update，并返回是否成功。boolean success = atomicLong.compareAndSet(100L, 200L);AtomicBooleanget(): 获取当前布尔值。boolean value = atomicBoolean.get();set(boolean newValue): 设置新布尔值。atomicBoolean.set(true);compareAndSet(boolean expect, boolean update): 如果当前值等于 expect，则将其更新为 update，并返回是否成功。boolean success = atomicBoolean.compareAndSet(false, true);AtomicReference<V>get(): 获取当前引用。V value = atomicReference.get();set(V newValue): 设置新引用。atomicReference.set(newValue);compareAndSet(V expect, V update): 如果当前引用等于 expect，则将其更新为 update，并返回是否成功。boolean success = atomicReference.compareAndSet(expectedValue, newValue);getAndSet(V newValue): 设置新引用并返回旧引用。V oldValue = atomicReference.getAndSet(newValue);AtomicMarkableReference<V>getReference(): 获取当前引用。V reference = markableReference.getReference();isMarked(): 获取标记。boolean marked = markableReference.isMarked();set(V newReference, boolean newMark): 设置新引用和标记。markableReference.set(newReference, true);compareAndSet(V expectedReference, V newReference, boolean expectedMark, boolean newMark): 如果当前引用和标记匹配 expectedReference 和 expectedMark，则更新为 newReference 和 newMark，并返回是否成功。boolean success = markableReference.compareAndSet(expectedReference, newReference, false, true);AtomicStampedReference<V>getReference(): 获取当前引用。V reference = stampedReference.getReference();getStamp(): 获取当前戳。int stamp = stampedReference.getStamp();set(V newReference, int newStamp): 设置新引用和戳。stampedReference.set(newReference, 1);compareAndSet(V expectedReference, V newReference, int expectedStamp, int newStamp): 如果当前引用和戳匹配 expectedReference 和 expectedStamp，则更新为 newReference 和 newStamp，并返回是否成功。boolean success = stampedReference.compareAndSet(expectedReference, newReference, 0, 1);
