I cannot add two BigDecimal objects-CodePudding

When I want to add two BigDecimal objects together

public void addBalanceWallet(BigDecimal balanceWallet) {
        this.balanceWallet.add(balanceWallet);
}

There is no effect. Additionally, the IDE shows

Why can't I add these two objects together?

CodePudding user response：

You are not assigning the return value (which is the actual result of the addition) to anything and thus the "Result (...) is ignored" message. I guess you want to do the following:

public void addBalanceWallet(BigDecimal balanceWallet) {
    this.balanceWallet = this.balanceWallet.add(balanceWallet);
}

CodePudding user response：

You have to save the return value. For example:

public BigDecimal addBalanceWallet(BigDecimal balanceWallet) {
        return this.balanceWallet.add(balanceWallet);
}

And afterwards:

BigDecimal addResult = this.balanceWallet.addBalanceWallet(some_big_decimal)
