If you use <a href="https://commons.apache.org/proper/commons-lang/" rel="noreferrer">Apache Commons Lang</a> (which I think a lot of projects use it), you can just use it like this: 

<pre><code>int myInt = BooleanUtils.toInteger(boolean_expression); 
</code></pre>

<code>toInteger</code> method returns 1 if <code>boolean_expression</code> is true, 0 otherwise

blocks|key|920400|text|这要视情况而定。通常，最简单的方法是最好的，因为它很容易理解：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|920401|if+(something)+{
++++otherThing+=+1;
}+else+{
++++otherThing+=+0;
}|code-block|syntax|javascript|920402|或|920403|int+otherThing+=+something+?+1+:+0;|920404|但有时使用枚举而不是布尔标志是很有用的。假设有同步和异步流程：|920405|Process+process+=+Process.SYNCHRONOUS;
System.out.println(process.getCode());|920406|在Java中，枚举可以有额外的属性和方法：|920407|public+enum+Process+{

++++SYNCHRONOUS+(0),
++++ASYNCHRONOUS+(1);

++++private+int+code;
++++private+Process+(int+code)+{

That depends on the situation. Often the most simple approach is the best because it is easy to understand:

<pre><code>if (something) {
 otherThing = 1;
} else {
 otherThing = 0;
}
</code></pre>

or

<pre><code>int otherThing = something ? 1 : 0;
</code></pre>

But sometimes it useful to use an Enum instead of a boolean flag. Let imagine there are synchronous and asynchronous processes:

<pre><code>Process process = Process.SYNCHRONOUS;
System.out.println(process.getCode());
</code></pre>

In Java, enum can have additional attributes and methods:

<pre><code>public enum Process {

 SYNCHRONOUS (0),
 ASYNCHRONOUS (1);

 private int code;
 private Process (int code) {
 this.code = code;
 }

 public int getCode() {
 return code;
 }
}
</code></pre>

blocks|key|1134829|text|如果您需要true+->+1和false+->+0映射，则可以执行以下操作：|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1134830|boolean+b+=+true;

If <code>true -&gt; 1</code> and <code>false -&gt; 0</code> mapping is what you want, you can do:

<pre><code>boolean b = true;
int i = b ? 1 : 0; // assigns 1 to i.

blocks|key|1135030|text|如果要进行模糊处理，请使用以下命令：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1135031|System.out.println(+1+&+Boolean.hashCode(+true+)+>>+1+);++//+1

If you want to obfuscate, use this:

<pre><code>System.out.println( 1 &amp; Boolean.hashCode( true ) &gt;&gt; 1 ); // 1
System.out.println( 1 &amp; Boolean.hashCode( false ) &gt;&gt; 1 ); // 0

<pre><code>public static int convBool(boolean b)

Then use :
