要在Java中检查两个数字是否相等，我们可以使用Equals（）方法以及==运算符。

首先，让我们设置整数。

Integer val1 = new Integer(5);
Integer val2 = new Integer(5);

现在，要检查它们是否相等，让我们使用==运算符。

(val1 == val2)

现在让我们看完整的例子。

示例

 

public class Demo {
   public static void main( String args[] ) {
      Integer val1 = new Integer(5);
      Integer val2 = new Integer(5);
      Integer val3 = new Integer(10);
      System.out.println("Integer 1 = "+val1);
      System.out.println("Integer 2 = "+val2);
      System.out.println("Integer 3 = "+val3);
      System.out.println("val1 is equal to val2 = "+(val1 == val2));
      System.out.println("val2 is not equal to val3 = "+(val2 != val3));
   }
}

输出

Integer 1 = 5
Integer 2 = 5
Integer 3 = 10
val1 is equal to val2 = false
val2 is not equal to val3 = true
