In Java, to compare two values for equality using BigDecimal, you can use either the compareTo method or the equals method.

  1. Utilize the compareTo method:
BigDecimal num1 = new BigDecimal("10.5");
BigDecimal num2 = new BigDecimal("10.5");

if(num1.compareTo(num2) == 0){
    System.out.println("两个值相等");
}else{
    System.out.println("两个值不相等");
}
  1. Utilize the equals method:
BigDecimal num1 = new BigDecimal("10.5");
BigDecimal num2 = new BigDecimal("10.5");

if(num1.equals(num2)){
    System.out.println("两个值相等");
}else{
    System.out.println("两个值不相等");
}

It is important to note that when comparing two values using BigDecimal, you should use the compareTo method or the equals method instead of using == directly. This is because using == directly to compare may result in loss of precision.
